List,
I seem to have hit a slight stumbling block in my mod_perl development.
Without wanting to write a whole essay on the exact combination of events
that causes this segv to happen I'll just say for now that it happens after
my custom Template::Provider returns a status indicating a template could
not be found. My apache error log indicates that the segv happens
immediately after my contenthandler returns SERVER_ERROR.
As you can see from the topic, the segv happens in the DProf library. I have
listed the gdb output at the end of my email.
My question is simply, is this a mod_perl problem, a template toolkit
problem or a problem somewhere in the dprof library?.
If I really need to use Apache::DProf then I'll just avoid requesting
templates that don't exist. I'm still curious however, as to whether there
is a more sinister problem waiting to cause my problems in the future.
Any advice? Has anyone else ever experienced a code path which causes a
similar segv in dprof?
Richard.
