I have not seen exrmaketiled behave this way.

Do you have an input file that makes exrmaketiled fail consistently,
or at least most of the time?  If so, send me the file, and I'll
try to reproduce the error.

Are the input files very large?  Is exrmaketiled possibly running
out of memory, or out of disk space?  In this case, the program
should abort with an error message, but I have been testing exrmaketiled
on a machine with lots of RAM and file space, so I don't know for
sure what happens.

What operating system are you using?
