If you have a reasonable place to dump the file you could just send a
link to the list. But I think you're getting ahead of things. What
actual failure is the program exhibiting? (Crash? Incorrect or no
output? Error messages?) Depending on what happens, a gdb backtrace or
an strace log may be more useful than the valgrind output.
