The previous commit (fix symbol resolution order) caused a regression -
tst-pipe.so stopped working, aborting on segfault while handling an
expected exception (one of the only places in OSV where we use an
exception to signal an error - running out of file descriptors).

However, it turns that commit just exposed an already existing bug
in our exception unwinding support. The following trivial test of
exceptions, throwing an integer and catching it, crashes both with
the previous commit, and without it.
