What are the recommended options to use (e.g., --enable-libsanitize) when
building GCC from source for the purpose of locating gfortran bugs? I'm
trying to pin down a runtime memory corruption error, and I recall seeing
at various times in the past recommendations for creating a suitable
gfortran build and the associated gfortran command line options for dumping
internal info, but I can't seem to find that info now.

Thanks!
