--- Comment #27 from Kostya Serebryany <kcc at gcc dot gnu.org> 2012-12-19 14:29:12 UTC --- This time it looks like a valid error report (stack buffer overflow), but asan crashes while reporting it. Take a look at DescribeAddressIfStack in asan/asan_report.cc, and see what does asan receive as frame_descr A small reproducer would really help me here.
