Description Sergey Zhukov 2015-11-19 04:08:21 UTC
I don't have fully reproducible test case yet, but this crash in GC occured when I tried in Monodevelop 5.11 (was got from master branch) to open Monodevelop solution file and then click (Version Control/Show Log and do some scroll). I did not notice such error on previous version of mono (4.0)

OS: Ubuntu Linux 12.04 32 bit
Mono JIT compiler version 4.2.1 (Stable Thu Nov 12 09:53:18 UTC 2015)

*** glibc detected *** /usr/bin/mono: double free or corruption (fasttop): 0x8f858dd8 ***

This is really strange, because the GC doesn't use malloc.

Could you install debug symbol for mono and attach a crash with symbol information?
The current one has no actionable information due to all symbols having being stripped.
