Mariano,
yes I was using the 64 bit pharo. I downloaded the 32 bit pharo 6.0 and it works just fine. Thanks.

Hi John,

Was this using 64bits flavor ? If true, can you try with 32 and let me know?��
I ask because I know OSSubprocess doesn't work on 64 bits yet, but to fix this I need some pull requets merged in the VM...

Cheers,

I got a seg fault when I tried to execute some OSSubProcess code in Pharo 6.0.

Namely,

| process |
process := OSSUnixSubprocess new
������ ������ ������ ������ command: '/bin/cat';
������ ������ ������ ������ redirectStdin;
������ ������ ������ ������ redirectStdout;
������ ������ ������ ������ run.
process stdinStream
������ ������ nextPutAll: 'we are testing!';
������ ������ nextPutAll: 'we again!';
������ ������ close.������ ������
process waitForExit.
process stdoutStream upToEndOfFile inspect.
process closeAndCleanStreams.

Attached is the crash.dmp file
