UBSan errors found in cmsGetColorSpace: not a valid value for type 'cmsColorSpaceSignature' about little-cms

Thanks for reporting. Indeed, this is not an error but the expected behavior. Remember this is C99 (not C++!) In C99 enums are assumed to fit in an int (32 bits in strict C99). You are compiling the code with clang++, which is not the required language.
Lcms allows to open profiles with custom color spaces, as an ICC extension, despite the number then is not listed in the enum. This is perfectly valid in C99.

Yes, i compiled it with clang++. The UBSan reported some errors confused me.

Thanks for your reply.
