There are many messages on comp.lang.c  You've said you're using gcc for
both Linux and Windows.  Which gcc based compiler are you using for Windows?
DJGPP? Cygwin? Mingw?  And, which version?

If DJGPP, then you've posted to the correct group.  DJGPP (which is gcc
based) v2.03 and v2.04 compiles the above code without the specified error.
The reason he asked about compile time is that _seems_ more like a runtime
error than a compile time error.  I.e., bad input to getchar might cause
such an error, but it seems unlikely the compiler would generate the error.

Maybe someone else has an inkling.  The only other thing I can suggest at
the moment is to try a different text editor and retype the code from
scratch.  Don't cut-n-paste.  Very rarely, an unusual character in the text,
e.g., from the cut-n-paste from the webpage, will cause problems for
compilers.  Rarely, certain text editors have problems too.  There are some
editors that will insert "bad" characters, insert nul's, or corrupt the
end-of-line marker.  If you're using a Windows editor, check to see if there
is a "save-as" option.  You might be able to save in different text only
formats.
