Whoops! No, not a compiler bug. It's a feature of your protected mode
environment and emx. :-)

Literal strings are (sensibly) placed into read-only memory, and strtok()
modifies the string, placing NULs into it. Either dupe the string within
the stoi_znnp() function or copy it to a temp buffer before passing to it.

Of course, it "works" under TurboC in real mode without any
memory protection. Had you used the strings more than once in your program
and if you had elected to fold string literals you would, however, run into
problems immediately.
