Developers please consider that Debian attempts to maintain binary compatibility with other Linux distributions and if you break "proprietary shit" that runs on other distributions then it could be your fault (especially when a new version of libc6 is rushed into unstable to fix it not being uploaded to experimental).
However it is completely understandable that only those who can run the
software can provide enough information to help you fix the problem. And
the original poster's bug report was poor.
A lot of proprietary software is never officially supported on Debian
GNU/Linux. One could only confidently tell a client that software will
run on an unsupported platform if these kinds of bug reports are taken
seriously. Otherwise the freedom to use a particular platform (and we
all know which the best one is) is completely lost for many users as
they are forced to use whatever Linux vendor and release version a
software company dictates.
I suspect Debian's founders had this in mind when writing section 5 of
the Social Contract. Without maintaining binary compatibility the mere
worry that one might need to run a proprietary program at some time in
the future could be enough to stop one using this platform. Even though
I have hardly used Win4Lin the mere fact it is available gave me the
confidence to remove the ability to boot into Windows a long time ago.
This is a tricky balance because there are significant costs that I
detest. I'm tied to a 2.4 kernel. I can't apply many types of kernel
patches. I can't give useful feedback in the event of a kernel panic. In
other words it kills the kinds of feedback and participation that helps
make free software successful.
It looks like you're got more important software in main to worry about
right now. In the meantime I'm sure Elmar and myself are happy to run
libc6 from testing. As it stands I'd suggest sid's libc6 problems are
release-critical and the severity level of this bug report should be
serious.
I don't want to spend any extra time trying to debug this so if the
following information is insufficient for you let NeTraverse sort it
out. Their mailing list is [EMAIL PROTECTED] and Richard Bass
<[EMAIL PROTECTED]>, Systems Software Architect, NeTraverse, Inc. is
very active on the list.
Upon booting win4lin tries to load its proprietary kernel modules. With
libc6 2.3.2-2 this happens:
Starting Win4Lin: /opt/win4lin/adminbin/rlock_tune: line 205: 712 Segmentation fault
"$STATICMERGE"/bin/max_sessions >>"$LOGFILE" 2>&1
max_sessions failed. Here is the output:

done.
I have attached a strace of what happens when one later tries to run
win:
strace -f -o strace.txt win
/bin/win: line 231: 1695 Segmentation fault winconfig $USE_CONFIG
list version >/dev/null 2>&1
/opt/win4lin/bin/win_probe: line 38: 1743 Segmentation fault
$STATICMERGE/publicbin/dosexec ++VLW $CONFIG 2>/dev/null
/bin/win line 231 is a call to:
check_config
The check_config function is:
check_config()
{
# Note:
# If the "win" configuration does already exist,
# AND the "dos" configuration does already exist
# then the winconfig command will silently and
# automatically create the default dos and win configurations.
winconfig $USE_CONFIG list version > /dev/null 2>&1

then
