It's

I'm running MD 2.25 on Solaris 8 SPARC, built with gcc 3.2 and
I've also been getting the same error:
     putc failed: Error 0 line 863

The problem is when *s = 0xff.
putc returns -1 == EOF

int putc(int c, FILE *stream)
     Upon     successful     completion,     fputc(),     putc(),
     putc_unlocked(),  putchar(),  and  putchar_unlocked() return
     the value that  was  written.   Otherwise,  these  functions
     return  EOF,  the error indicator for the stream is set, and
     errno is set to indicate the error.

Sorry I'm not fluent enuf in C to suggest a fix.

Hope this helps
