If the input buffer exceeds the stack auxiliary buffer, qsort will malloc a temporary one to call mergesort. Since C++ standard does allow the callback comparison function to throw [1], the glibc implementation can potentially leak memory. The fixes uses a pthread_cleanup_combined_push and pthread_cleanup_combined_pop, so it can work with and without exception enables. The qsort code path that calls malloc now requires some extra setup and a call to __pthread_cleanup_push anmd __pthread_cleanup_pop (which should be ok since they just setup some buffer state). Checked on x86_64-linux-gnu. [1] https://timsong-cpp.github.io/cppwp/n4950/alg.c.library#4 Reviewed-by: DJ Delorie <dj@redhat.com> |
