Okay, strangely setting a break point to initialiseModule, put it on SurfacePlugin
(gdb) break initialiseModule Breakpoint 1 at 0x811acc8: file
/home/hilaire/Travaux/pharo/temp/COG/platforms/Cross/plugins/SurfacePlugin/SurfacePlugin.c, line 204.
I have to start the VM then quit, then adding again a break point on initialiseModule set it to locale:
Program exited normally. (gdb) break initialiseModule Breakpoint 5 at 0x559542: file
/home/hilaire/Travaux/pharo/temp/COG/src/plugins/LocalePlugin/LocalePlugin.c, line 112.
step throught the function is:

You'll need to state (gdb) handle SIGALRM nostop noprint noignore first. Â In fact, do that for most signals. Â What's happening below is gdb stopping on delivery of the 1KHz heartbeat, so you won't get far without ignoring it.
yeah.. i also were stuck with this cruelty before.. trying to step instruction-wise and was always interfered by heartbeat thread :)
