On Mac, run Valgrind with the following options.
--smc-check=all-non-file --vex-iropt-register-updates=allregs-at-mem-access --show-mismatched-frees=no --dsymutil=yes
The --dsymutil option ensures line number information is present in stack traces.

--smc-check=all-non-file --vex-iropt-register-updates=allregs-at-mem-access --show-mismatched-frees=no --read-inline-info=yes
The --smc-check and --vex-iropt-register-updates options are necessary to avoid crashes in JIT-generated code.
The --show-mismatched-frees option is necessary due to inconsistent inlining of new and delete -- i.e. one gets inlined but the other doesn't -- which lead to false-positive mismatched-free errors.
The --read-inline-info option improves stack trace readability in the presence of inlining.
Also, run with the following environment variable set.
G_SLICE=always-malloc
