Hi,
After building apache with --shared-module=max and building mod_perl using
apxs, I get some strange behavior. I've also built my perl with -g
-DDEBUGGING.
On starting the web server, I get a bunch of "Bad free() ignored."
messages that seem to occur at the end of every block of perl code (ie.
scripts, loaded modules, etc.). Then the server segfaults. Using httpd -X
and gdb I've found that it cores when trying to do a dlclose() on the
mod_perl shared library.
Does anyone have an insights as to what might be happening? Backtrace
below.
Thanks,
