Dear all
I know, this is topic everybody is fed up with and that it has been
discussed ad nauseum. Still, I can't figure out what's going on...
Here the symptoms:
* Trying to run a shell command from Python fails 50% of the time
with: address space needed by 'cygz.dll' (0x450000) is already
occupied. So far only Python shows this problem. E.g. the following
simple snippet regularly fails:
>>> import subprocess
>>> subprocess.check_call('sleep 1'.split())
* rebaseall doesn't help (even tried a fresh installation of Cygwin, a
clean PATH, etc).
* rebase -si only shows an asterisk for the following entries:
/usr/bin/cygperl5_14.dll base 0x0003fe9b0000 size 0x00190000 *
/usr/lib/perl5/5.14/x86_64-cygwin-threads/CORE/cygperl5_14.dll base
0x0003fe9b0000 size 0x00190000 *
Given that they both belong to the same package and have the same
name, I tend to think that this is a spurious message that has nothing
to do with my problem. Nothing suspicious about cygz.dll in the output
(at least as far as I can tell).
* The 32-bit Cygwin installation is fine and never shows this behavior
Anybody got an idea how to get to the bottom of this problem?
Cheers
Michael
