Comment (by teor):

 This set of flags also works fine:
 `-O2 -funroll-loops -ffp-contract=on -fno-omit-frame-pointer -mrelax-all
 -fstrict-aliasing -Wstrict-aliasing  -arch x86_64`

 Leaving me with the following (deduplicated) potential problematic
 options:
 `-fasynchronous-unwind-tables -fno-optimize-sibling-calls -fno-inline
 -fstack-protector-all -fsanitize=undefined -fno-sanitize-recover=all
 -fsanitize=address -O0`

 I'll do some builds with each option and see.

 If the sanitizers are the issue, I'll add the problematic code to:
 `-fsanitize-blacklist=contrib/clang/sanitize_blacklist.txt`
