Mike, could you run the reproducer under Valgrind?
This looks like a very likely dup of PR 13579 (which has a trivial test case).

valgrind log for aplay/libasound
Mike mentioned mpd, which I guess uses libasound. The attached log is
from aplay/libasound. I put debugging statements into libasound to
flag all of its calls to the dl* functions in libdl.

That is an exact match to PR 13579.

It's certainly a very close match, but notice one thing: in
libasound all the calls to dlopen use mode 2 (RTLD_NOW), which
differs from the test case for bug 13579. I tried making a
simple test case which emulated libasound's pattern of calls
to the dl* functions (using RTLD_NOW with dlopen) and it
ran fine with stock glibc 2.15, no crash. For what it's worth.

Ran fine with no Valgrind errors?
(Not every access to dangling memory causes a crash.)
