 > It sounds like those ports individually need to have their
 configurations modified to set `-D CMAKE_CXX_FLAGS_RELEASE="-O0"`. When a
 default autoconf variable causes a port to fail to compile, the "fix"
 isn't to patch the defaults in the autoconf port, is it?

 The fix is to make sure that those ports build with the correct
 optimization flags (configure.optflags) rather than -O3.
