Known problem with the assembler in Solaris 2.6.

Welcome to bug 4237974; the 4.2 assembler can't handle really long symbol
names.  The symbol on that line (involving a pair<something> constructor,
I think) is over 2KB in length.  I think the limit on that assembler was
1K or half a K.

Patch 108908-02 fixes this.  It's also been integrated into more recent
(5.x and later) solaris tools.

On the g++ end, there's a new mangling scheme somewhere that creates much
shorter names.  I don't know offhand if it's already in place, or dropped,
or in the new ABI, or what.
