If this helps my problems are on:
Redhat 6.2 I've libstdc++-2.9.0-30 and it has the above bug on kernel
2.2.17 and 2.4.2 complie with gcc -v of
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release).
SUSE 7.0 libstdc is not install - bug still apears gcc is gcc version
2.95.2 19991024, Kernel 2.2.16
