After upgrading to glibc 2.10.1-r1 from glibc-2.9_p20081201-r2, I got segmentation fault with some proprietary software. Using gdb with backtrace it stops at strlen(). Bumping the version to 2.11-r1 the problem disappears. Reproducible: Always Steps to Reproduce: 1. emerge glibc 2.10.1-r1 2. run proprietary software 3. Crashes while calling strlen() Actual Results: Program crashed. Expected Results: Software should have run as before.
