Hi all, first, thanks for the great tool, especially the address sanitizer. I have a multi-threaded program, where I get a segfault due to access to free'd memory in one thread. In the report, I see references to where this memory block was malloc'ed and free'ed. Unfortunately, these later two stack traces just include 2 and 3 stack frames, where it would need to be around 15. Most importantly, the information I really need is missing due to that.
I tried to explicitely set ASAN_OPTIONS=verbosity=1:malloc_context_size=20 even though malloc_context_size should be 30 by default. I know ASAN_OPTIONS is used, because my output now is verbose. I compile with -g -W -Wall -Wformat-security -Wshadow -Wcast-align -Wpointer-arith -Wmissing-format-attribute -fsanitize=address -fno-omit-frame-pointer -O0 Note that I added -O0 in a desparate effort to try to get to larger stack traces. Nothing changes if I leave it out. I than wrote a small single-threaded test program, and there large stack traces are reported. Does anyone have any advise on how to get to larger stack traces? Or at least what could be the root cause of this problem? Any help would be deeply appreciated.
