[Bug c++/18363] New: build fails when using optimization

[gcc-bugzilla at gcc dot gnu dot org]

	The same code builds without the -O flag but gcc 'crashes' when adding optimization...
	I wasn't sure if I had to include the binary Config.ii.bz2 in this mail... I'm using gccbug so it seems a bit odd to include binary data here.
	Instead I uploaded it, you can download it here: http://aphexer.dyndns.org/bug/Config.ii.bz2 (in the same directory there are some other maybe
	interesting files).

Environment:
System: Linux slack 2.4.26 #21 Mon Jun 14 19:17:44 PDT 2004 i686 unknown unknown GNU/Linux
Architecture: i686

	
host: i486-slackware-linux-gnu
build: i486-slackware-linux-gnu
target: i486-slackware-linux-gnu
configured with: ../gcc-3.3.4/configure --prefix=/usr --enable-shared --enable-threads=posix --enable-__cxa_atexit --disable-checking --with-gnu-ld --verbose --target=i486-slackware-linux --host=i486-slackware-linux

How-To-Repeat:
	I use this to compile: g++ -Wall -save-temps -DHAVE_CONFIG_H -I. -I. -I../.. -g -O -MT Config.o -MD -MP -MF ".deps/Config.Tpo" -c -o Config.o Config.cpp

Fix:
	Remove the -O argument.

Created an attachment (id=7490)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=7490&action=view)
this generates the error....

Didn't know I could attach this here... So now I did :) You can download
related code at http://aphexer.dyndns.org/bug/ (in case you want to see what I
actually wrote, this preprocessed thing seems a bit cryptic to me :))

Can this be caused by insufficient memory? This machine only has 32MB of ram...

Now it's on that next file but it's the same error:

".deps/HFormat.Tpo" -c -o HFormat.o HFormat.cpp; \
then mv -f ".deps/HFormat.Tpo" ".deps/HFormat.Po"; else rm -f
".deps/HFormat.Tpo"; exit 1; fi
g++: Internal error: Killed (program cc1plus)
Please submit a full bug report.

Yes this is a case where 32M is just too little for compiling C++ code in 3.3, you might want to try 3.4.

Isn't this error a bit misleading? Something like "Not enouph memory,
aborting..." seems alot more clear! Maybe this is something which can be changed
for a next release?

Well my problem is actually solved... just add more ram :)

Maybe it's a good idea too put another note on the checklist before reporting a
bug: "do you have enouph ram? (check with 'free' while compiling)".

Thanks for helping.

g++: Internal error: Killed (program cc1plus)

The kernel is killing cc1plus for hitting memory limits and not gcc crashing.
