Subject: Some zlib/popen bugs in 1.5.2/Solaris !

After the change from 1.5.2b2 to 1.5.2 I encountered serveral problems
in the official release. The test suite fails in the test_zlib and
the test_popen2 module.

Traceback from test_zlib:

(gdb) run

bonnie@/ojs/home/ojs/src/Python-1.5.2(90)%  ./python Lib/test/test_popen2.py
testing popen2...

Traceback (innermost last):

All tests are reproduceable using egcs-1.1.2 and egcs-2.95 under Solaris 2.6.

Any idea ?
