Crashes in `free` usually mean there's heap corruption. And with heap corruptions, the stack-trace of the crash often has nothing to do with the actual bug. The most likely reasons for heap corruptions are out-of-bounds writes and use of dangling pointers. Daniel's suggestion to use valgrind/ASAN is a good one - those tools should help you find the cause. Count yourself lucky that you can repro the problem by just running the program for 5-10 minutes š The contents of this e-mail are intended for the named addressee only.
