In building your repro case, you'll need to toggle several flags to see how to trip this up;
- CMAKE_C_FLAGS_RELEASE:STRING=/MD /O2 /Ob2 /DNDEBUG + CMAKE_C_FLAGS_RELEASE:STRING=/O2 /Wall /Zi I'd start with your problem case /O2 /Wall /Zi, and retest adding /Ob2, /MD and /NDEBUG in that order. Simply slice and dice until you find the flags which cause the negative min limit to fail ERANGE, but the positive max case to not toggle errno.
