When trying to debug my C++ binary, I am running into the following issue. valgrind: m_mallocfree.c:307 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind : Heap block lo/hi size mismatch: lo = 1, hi = 4294967295. This is probably caused by your program erroneously writing past the end of a heap block and corrupting heap metadata . If you fix any invalid writes reported by Memcheck, this assertion failure will probably go away . Please try that before reporting this as a bug. host stacktrace : ==1747== at 0x58013284: ???

If my source binary has a memory link (as per Valgrind FAQs) I am puzzled as to why I am not encountering the issue when not running in a container. Any help appreciated. -Karthik _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
