Hi:

After an upgrade from RedHat 5.2 to 6.0 a problem apear with a
program.
We compiling this program the process cc1plus starts "eating"
all
the
memory.

The system is a Dell PowerEdge 1300 (2 x Pentium III with
512MB)
with
Redhat 6.0 default server instalation and all egcs packages
(egcs-1.1.2-12...).

Command line: g++ bug.cc

The result: sometimes the system is hanged, sometimes the
compiling
process stop with a error message:
        bug.cc:118: virtual memory exhausted

After this error, I went back to a Redhat 5.2 system and every
was ok.
The problem isn't the machine, we have test it on several
(Pentium II,
amd k6, pentium III) Redhat 5.2 systems (with egcs-1.0.3). In
the
same
machines with Redhat 6.0 the error apear always.

Thanks

Gustavo

PS: the error disappear when deleting "= Fitness()" in the declaration
of Pair.
