It looks like it's trying to apply a relocation to a read-only part of
the mapping. Could you provide the output of readelf -a testapp? That
would let me get an idea what's going on. It's probably too big to
send as an attachment raw but compressing it with gzip will probably
make it okay, or you could just send a link to a pastebin or similar
(sprunge.us preferred).
