Two crash backtraces in this mail. Does anyone have an idea what might be
wrong there?
Simply linking any Audacious plugin with -lprojectM leads to a segfault on
application exit. In other words, even if the library is not used but just
linked with, app exit segfaults. That's an indication that something in
the library, which is initialized when the run-time linker binds the app
with the library, gets destroyed on exit and then crashes in the
std::basic_string destructor. Building the packages for Fedora 13, it's
reproducible. Audacious upstream (uses Ubuntu and/or Debian) cannot
reproduce it, however.
$ audacious

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Fedora 13's ABRT (Automatic Bug Reporting Tool) doesn't manage to catch
these crashes. If I just link an arbitrary Audacious plugin with
-lprojectM (and really without doing any API calls), the backtrace
is a bit different:
