[Pkg-clamav-devel] [sparc] Bus error in _dl_new_object

Sun Mar 29 12:57:40 UTC 2009

Package: libc6
Version: 2.9-6

Here's another problem that popped up while running clamav's test suite. Again's
there a problem loading /usr/lib/gconv/UTF-16.so (as in #521556), but here I'm
unable to really see which pointer is invalid because gdb refused to provide any
information about the objects used in line 110 of dl-object.c (new or
dl_load_adds). Below is all I got from gdb.

Best,
Michael
