	Hi,

 	I've seen on the egcs-bugs list that someone else has 
reported a similar misbehaviour of cc1plus (November_1997::
"Memory leak with -O -Wall" by P.Schmid) on a i386-glibc1. 

This rings me bell !. 
In an earlier version of egcs, memory was not released during 
during the instatiation of templates and someone provided 
a patch against. This bug back may be in the current release !?
That my .002cents. Sorry that's all I can do; don't know 
about a compiler internals. 

Thanks.

Regards, Max


P.S. Mumit Khan noticed a difference between our testsuite results.
I have a typename5.C failure he didn't have with the current snapshot 
and I didn't have with the previous one. Is it related to the problem 
above ?
