Ok, but I'm afraid you'd need to add this to the docs and inform such projects as: SQLite, PCRElib, libxml2 and many more which do not cast it to (unsigned char) either.
Currently I can see similar "expected" behaviour only on Solaris, which also segfaults in this case.
Other systems (AIX, MacOS, various Linuxes) have chosen a user-friendly way and return 0.
