So the implication is that some files do have their src saved, and some don't. So you need to look at the list of those that do and don't and try to determine what's common about those that don't. Perhaps they're loaded in a different way, or perhaps the 'with src' only applies to the first N files. I don't know.

No need, I can reproduce it: NYTPROF=savesrc=1:use_db_sub=1:compress=0 perl -d:NYTProf -e 'use warnings;' fwrite error 2: No such file or directory at /usr/local/perl58-i/lib/site_perl/5.8.6/darwin-thread-multi-2level/Devel/NYTProf.pm line 39. BEGIN failed--compilation aborted at /usr/local/perl58-i/lib/5.8.6/warnings.pm line 134. It's very odd that changing any of those three options makes the problem go away. Very odd. I'll go dig...
