g++ 2.91.66 bug report

[Mike <mike at notthebox dot com>]

This looks like a sporadic compiler bug that seems to occur on any of my
c++ code that makes use of streams.

GCC Version:
===========
egcs-2.91.66 [stock install from RedHat 6.1 RPMS]

System Type:
===========
Redhat 6.1 on i386 (linux kernel: 2.2.12-20)

Compiler Line:
==============
[mike@cr248721-a hello2cpp]$ g++ -v --save-temps -Wall -o hello2
hello2.cpp

Preprocessed Output
===================
(included: hello2.ii.gz)


Compiler stdout

Details
=======
This bug is strange. If I try to compile it several times in a row with an
identical g++ command, I get varying results. Sometimes it compiles, and
the rest of the time I get compiler errors on one of the cout lines.

I checked the egcs /bugs.html page, and didn't see anything that looked
too much like this.

This file consistently compiles correctly on a sparc/solaris2.6 running
gcc 2.8.1.



Question: are there RPMS available for egcs-2.95? If so, I'll upgrade.



thanks,
