It works ok for me (except for the extra ">" char on the close line). I made a multipath.tr file consisting of

one
two
three

Of course, this doesn't look like what the program wants to process, so my output is:

in while...1
in while...1
in while...1
0

but you can see that it is processing the loop. If your multipath.tr file is empty, the loop would never execute. Is that possibly what's going on?
