Hi - thanks for the bug report. Valgrind currently does not support macOS 10.15, with a substantial amount of work to go. See further tracker bug at bz#412745. Couple of questions: - What out of tree patches have you applied to valgrind to get it to build? (I presume that you build your own version of valgrind from the below log). - What is the target program that you are tracing? If proprietary, can you recreate the same log/errors with a simple C program that you can share here. Actually, the specific error message you reported is already tracked here at bz#402696 (tzset) due to valgrind missing support for a mach call. However, I'd still be interested in your feedback on the other questions. I'll leave this bug report open for a little while, but the main error reported in your log is a duplicate of bz#402696. |

It contains workarounds to several common problems. In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks.
