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. -- http://sourceware.org/bugzilla/show_bug.cgi?id=10282 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
