Description of Problem: With glibc-2.4.4-19-i686 Quake3 Arena crash with sound enabled on signal 11. Sound disabled works ok. glibc-2.4.4-19-i386 works fine with or without sound. With gdb I've found out it crash is memset function. Version-Release number of selected component (if applicable): glibc-2.4.4.-19-i686 How Reproducible: always Steps to Reproduce: 1. enable sound 2. run quake3 3. signal 11 is reported Actual Results: Expected Results: Additional Information:
If it crashes in memtest, it means somebody passed it a wrong pointer or correct pointer but too large size so that it fell off the cliff. If there was a bug in memset, you'd notice it far earlier. So this looks like a quake3 bug.
Quake3 with sound fails with Signal 11 for me with glibc-2.2.4-19 with both the i386 or i686 versions (this is on an Athlon system). I'm not certain this can be regarded as strictly a Quake3 bug because using LD_PRELOAD to load a simple memset() function instead of glibc's causes sound to work. Also, Alan Cox posted on slashdot that this is probably a glibc optimization bug.
