I don't think I understand your description, but maybe running Emacs
under GDB with a breakpoint in Fload, with a condition that it will
only break when the offending file is loaded, will allow you to
produce a backtrace, and we could then take from there, armed with the
list of possible offenders -- the functions in the backtrace.
