Hi all,

When I try to run m4 on my Mac, it immediately fails with

Abort trap: 6

I built using the traditional ./configure ; make -j8 and then run it with

./src/m4

This is the result of gcc --version:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 11.0.0 (clang-1100.0.33.12)
Target: x86_64-apple-darwin19.0.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Thanks!
