Try to add ASAN_OPTIONS=fast_unwind_on_malloc=0. It's possible that stack
traces go through smth. like libstdc++ which is built without frame
pointers.

Short update: I thought the behavior reported below it might be related to the
fact that llvm-symbolizer picks up the “wrong” (i.e. the msan-implemented)
version of libc++ once I put it in the LD_LIBRARY_PATH. Thus I tried to compile
a complete LLVM/Clang stack (with compiler-rt, libcxx, libcxxa
Hi folks,
When running our msan-instrumented simulation program, instead of a proper

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 sta
