Dear maintainers,
in https://lists.gnu.org/archive/html/bug-m4/2019-11/msg00005.html,
Vanessa McHale wrote that m4 built under macOS fails with "Abort trap: 6".
When I try that, I get "Abort" and a return code 134.
Here's a backtrace:
(lldb) run

I also tried to build and run older versions. The last verrsion that works
for me is 1.4.11. With 1.4.12, the error occurs.
If there's anything else I can do please let me know. I'm not subscribed
to the list.
Thank you,
Rainer
