If a profiled program terminates with profiling disabled, it appears to result in a corrupted nytprof.out file. I came across this while attempting to selectively profile a page served out of an Apache Mason setup. The following 3 failure cases result in an exit code of 255, and a malformed nytprof.out file, which nytprofhtml subsequently barfs on with: Generating report... inflate failed, error -5 ((null)) at end of input file - is it truncated? at /usr/lib/perl5/site_perl/5.8.8/i586-linux-thread-multi/Devel/NYTProf/Dat line 74. I also include a success case which demonstrates that leaving profiling enabled at termination results in a clean exit (and a good nytprof.out file).
