Comment 21 for bug 425723

I just wanted to point out that the bug is still present in glibc 2.11. The
second proposed patch works for me in both the testcase and (so far) in my KDE
workspace with MALLOC_CHECK_ enabled.

This bug is a concern for KDE developers because development versions of KDE
automatically set MALLOC_CHECK_ for glibc systems to attempt maximize early
error detection. It's hard when merely enabling mcheck causes crashes of its
own though. Something in the combination of Qt4+glib and a couple of other KDE
programs (like Okular, KTorrent, and KNotify) trips across this race quite
frequently.

Since there appears to be a fix I'll go ahead and inform the KDE development
community so we can push for the fix to be implemented in distribution packages
while it's debated for glibc.
