This was discussed in an earlier thread[2] and the conclusion seemed to 
be that building with --enable-fully-dynamic-string[3] works around[4] 
this bug, and that gcc would be rebuilt[5] with it.  I've built it as 
such as well and verified that it does seem to fix the bug, and have 
also made some m4 for autoconf[6] to detect if the bug exists at 
configure time.

The discussion on 10/2005 seems to have stalled without a new gcc built 
with --enable-fully-dynamic-string being distributed.  Can gcc get 
rebuilt with this option?
