UndefinedBehaviorSanitizer's Unexpected Behavior

I believe AIX C++ name mangling includes function argument type information (with CV qualifiers!) so this is a real-world case where this does actually break. I suspect curl does not compile with the C++ compiler though.

So does the Itanium ABI (which is what most people would think of as the normal/standard/usual C++ ABI):

  $ c++filt
  _Z1fPFvPcE
  f(void (*)(char*))

But I'm struggling to understand how this would cause things to break.

I guess only if you directly expose C++ APIs in DLLs, which is a bad idea anyway.
