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`
