Mailing List Archive: os.popen2() test croaks on python 1.5.2, Solaris 2.6

Hi,

I just compiled python 1.5.2 on Solaris 2.6 using gcc (egcs-1.1). I ran "make
test" and got this error:

% python
Python 1.5.2 (#3, May 11 1999, 13:39:27) [GCC egcs-2.91.57 19980901 (egcs-1.1 re on sunos5

>>> import popen2
>>> popen2._test()

testing popen2...
testing popen3...
Traceback (innermost last):
File "<stdin>", line 1, in ?
File "/home/mvanier/local/Solaris/lib/python1.5/popen2.py", line 95, in _test
assert not _active
AssertionError

I don't actually use the popen2 module, but this looks like a bug. Weirder
still, when I ran it from within IDLE it worked! Any ideas?

Thanks,

Mike

It works on mine. Maybe it's the egcs compiler?

Have you tried to trace thru the popen with pdb? (careful of the fork).
