Hi, I wanted to see FileSystem's coverage, so I * downloaded 3.0 via curl http://get.pharo.org/30+vm | bash, * fired up the image, * opened the TestRunner, * highlighted the three FileSystem packages, * "select all"ed, * pressed "Run Coverage" and the VM crashed with a segfault. I tried with a few other packages, and every time I tried to run coverage the VM died with the same message: Segmentation fault Sun May 26 15:46:45 2013 pharo VM version: 3.9-7 #1 Wed Mar 13 18:22:44 CET 2013 gcc 4.4.3 Built from: NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 With: NBCogit NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 Revision: git://gitorious.org/cogvm/blessed.git Commit: 412abef33cbed05cf1d75329e451d71c0c6aa5a7 Date: 2013-03-13 17:48:50 +0100 By: Esteban Lorenzano <estebanlm@gmail.com> Jenkins build #14535 Build host: Linux linux-ubuntu-10 2.6.32-38-server #83-Ubuntu SMP Wed Jan 4 11:26:59 UTC 2012 x86_64 GNU/Linux plugin path: /home/frank/Downloads/pharo-3.0/pharo-vm/ [default: /home/frank/Downloads/pharo-3.0/pharo-vm/] C stack backtrace: pharo-vm/pharo[0x80a0c0c] pharo-vm/pharo[0x80a0f28] [0x408410] [0x77744f1e] [0x777447c8] [0x7819010f] [0x777454f9] [0x777447c8] [0x7818e112] [0x777fc687] [0x777456ea] [0x77744668] Smalltalk stack dump: 0xbfc98e4c I [] in InteractiveResolverTest(TestCase)>runCase 0x78f0bfc8: a(n) InteractiveResolverTest 0xbfc98e6c M BlockClosure>ensure: 0x78fa4c34: a(n) BlockClosure 0xbfc98e90 I InteractiveResolverTest(TestCase)>runCase 0x78f0bfc8: a(n) InteractiveResolverTest 0xbfc98eb4 I [] in TestResult>runCase: 0x78f0bdcc: a(n) TestResult 0xbfc98ed0 M BlockClosure>on:do: 0x78fa4a30: a(n) BlockClosure 0xbfc98ef8 I TestResult>runCase: 0x78f0bdcc: a(n) TestResult 0xbfc98f1c I InteractiveResolverTest(TestCase)>run: 0x78f0bfc8: a(n) InteractiveResolverTest 0xbfc98f3c M [] in TestSuite>run: 0x78f0bfb0: a(n) TestSuite 0xbfc98f5c M OrderedCollection>do: 0x78f0bfdc: a(n) OrderedCollection 0xbfc9fdf0 I [] in TestSuite>run: 0x78f0bfb0: a(n) TestSuite 0xbfc9fe10 M BlockClosure>ensure: 0x78fa48e4: a(n) BlockClosure 0xbfc9fe34 I TestSuite>run: 0x78f0bfb0: a(n) TestSuite 0xbfc9fe58 I [] in TestRunner>runSuite: 0x78e405bc: a(n) TestRunner 0xbfc9fe80 I BlockClosure>cull:cull: 0x78f9c050: a(n) BlockClosure 0xbfc9feb0 I [] in TestRunner>executeSuite:as: 0x78e405bc: a(n) TestRunner 0xbfc9fed0 M BlockClosure>ensure: 0x78f9c420: a(n) BlockClosure 0xbfc9fef4 I TestRunner>executeSuite:as: 0x78e405bc: a(n) TestRunner 0xbfc9ff1c I TestRunner>runSuite: 0x78e405bc: a(n) TestRunner 0xbfc9ff3c M [] in TestRunner>collectCoverageFor: 0x78e405bc: a(n) TestRunner 0xbfc9ff5c M BlockClosure>ensure: 0x78f9bfcc: a(n) BlockClosure 0xbfc97e54 M [] in TestRunner>collectCoverageFor: 0x78e405bc: a(n) TestRunner 0xbfc97e74 M BlockClosure>ensure: 0x78f0dd7c: a(n) BlockClosure 0xbfc97ea8 I BlockClosure>valueUnpreemptively 0x78f0dd7c: a(n) BlockClosure 0xbfc97ed4 I TestRunner>collectCoverageFor: 0x78e405bc: a(n) TestRunner 0xbfc97ef8 M TestRunner>runCoverage 0x78e405bc: a(n) TestRunner 0xbfc97f18 I PluggableButtonMorph>performAction: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc97f38 M [] in PluggableButtonMorph>mouseUp: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc97f5c M Array(SequenceableCollection)>do: 0x78ed9f14: a(n) Array 0xbfc93e08 M PluggableButtonMorph>mouseUp: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc93e28 M PluggableButtonMorph(Morph)>handleMouseUp: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc93e44 M MouseButtonEvent>sentTo: 0x78ed9eec: a(n) MouseButtonEvent 0xbfc93e60 M PluggableButtonMorph(Morph)>handleEvent: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc93e7c M PluggableButtonMorph(Morph)>handleFocusEvent: 0x78e6c24c: a(n) PluggableButtonMorph 0xbfc93ea4 M [] in HandMorph>sendFocusEvent:to:clear: 0x77b1c270: a(n) HandMorph 0xbfc93ec0 M [] in PasteUpMorph>becomeActiveDuring: 0x7796b824: a(n) PasteUpMorph 0xbfc93edc M BlockClosure>on:do: 0x78ed9e5c: a(n) BlockClosure 0xbfc93f08 M PasteUpMorph>becomeActiveDuring: 0x7796b824: a(n) PasteUpMorph 0xbfc93f2c M HandMorph>sendFocusEvent:to:clear: 0x77b1c270: a(n) HandMorph 0xbfc93f54 M HandMorph>sendEvent:focus:clear: 0x77b1c270: a(n) HandMorph 0xbfc92e44 M HandMorph>sendMouseEvent: 0x77b1c270: a(n) HandMorph 0xbfc92e68 M HandMorph>handleEvent: 0x77b1c270: a(n) HandMorph 0xbfc92e94 M HandMorph>processEvents 0x77b1c270: a(n) HandMorph 0xbfc92eac M [] in WorldState>doOneCycleNowFor: 0x7797ab44: a(n) WorldState 0xbfc92ed0 M Array(SequenceableCollection)>do: 0x77846894: a(n) Array 0xbfc92eec M WorldState>handsDo: 0x7797ab44: a(n) WorldState 0xbfc92f08 M WorldState>doOneCycleNowFor: 0x7797ab44: a(n) WorldState 0xbfc92f24 M WorldState>doOneCycleFor: 0x7797ab44: a(n) WorldState 0xbfc92f40 M PasteUpMorph>doOneCycle 0x7796b824: a(n) PasteUpMorph 0xbfc92f60 I [] in MorphicUIManager>? 0x7797ebd4: a(n) MorphicUIManager 0x77c9891c s [] in BlockClosure>?
