bug report ?

[Xavier Bertou <bertou at iap dot fr>]

Hi...
I'm trying to compile kde with egcs 971122.
Compiling kdelibs 
(kdelibs-Beta2-1.src.tgz)
On a : OSF1 lirac V4.0 564.32 alpha

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
lirac-/home/champigny2/isogal/bertou/install/kdelibs  make
No suffix list.
make all-recursive
No suffix list.
Making all in kdecore
/home/champigny2/isogal/bertou/lirac/qt/bin/moc kconfig.h -o kconfig.moc
/bin/sh ../libtool --mode=compile g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/home/champigny2/isogal/bertou/lirac/qt/include   -O2 -Wall -c kconfig.cpp
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/home/champigny2/isogal/bertou/lirac/qt/include -O2 -Wall -c -DPIC kconfig.cpp
kconfig.cpp: In method `bool KConfig::writeConfigFile(class QFile &, bool = false)':
kconfig.cpp:254: Internal compiler error.
kconfig.cpp:254: Please submit a full bug report to `egcs-bugs@cygnus.com'.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

I have no idea what a full bug report is, but as I am asked to do it, I try to do my best :
Here are the files kconfig.cpp and kconfig.moc :
Hope it helps ( I can give other informations if someone asks..)
