System: Linux aris.dummy.de 2.4.4 #1 Mon Mai 7 00:17:52 CEST 2001 i686 unknown
Architecture: i686

	self-built Athlon-1200, 128MB DDR-RAM, AMD761 chipset, Linux (s.a.)
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc-3.0/configure --prefix=/usr
	Trying to compile a Mozilla snapshot (CVS from about
	10 minutes ago), gcc3 crashes like this:
	nsFormControlHelper.cpp: In static member function tatic void
	nsFormControlHelper.cpp:733: Internal error: Speicherzugriffsfehler
	Please submit a full bug report,
	with preprocessed source if appropriate.
	See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
	(this is the output of my reproduced crash)

	I extracted the whole source that lead to the problem using
	g++ -E; every g++ options higher than -O2 cause this problem
	(-O2 is ok, -O3 crashs)
	Really don't know. I saved the -E'd file with which this crash
	is reproducible; it's about 720k in size; please contact me if
	you want me to send it to you.
	The machine is ok (I even changed the whole memory, motherboard
	and CPU today and had this g++ crash before and after; no
	overclocked or somewhat else abused components inside)
