According to posts from 2008 (I can't find it right now), glibc heap check doesn't work in multithreaded environment. Is it still situation now in 2010?
Does heap check enabled by default? (gcc 4.1.2)? I don't set MALLOC_CHECK_, don't aware of calling mcheck(), but still sometimes receive double free glibc error with backtrace. Maybe it's enabled by some ccompilation flag?
