On both IronPython 1.0.1 and IPCE release 4, os.popen() segfaults
under Mono 1.17.1 (on Ubuntu edgy).
To reproduce:
ipy.exe -c "import os; print os.popen('/bin/ls', 'r').read()"
Stacktrace follows, for whatever value it is... I can't tell
immediately whether it's an IronPython or Mono problem, although it
_appears_ to be in Mono. If other people agree, I'll log a Mono bug
tomorrow.
It looks like most of the os module to do with spawning commands is
missing, apart from os.spawnl(), which _appears_ to work. It should be
possible to re implement the stdlib's popen2 module on top of that.
Whether it will work is another matter entirely, of course :-)
=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
