Bugzilla Bug 9336

Strange behaviour while compiling kdebase and kdelibs: They freeze my whole 
system at some point. There's no way to shut down savely, I have to do a 
hard reset; there haven't been any problems building other big apps (e.g. 
gimp-1.3.9). I disabled grsecurity as it sometimes causes problems with 
some applications but that also didn't help. Hardware is ok (no bad RAM, no 
CPU overheat or overclock, new harddisk). Possibly it's a g++ issue when 
compiling bigger apps written in c++. If you only could reproduce this 
behaviour...

hardware specs:
Athlon 800 TB
512 MB Infineon Ram ;-)
Asus A7V-133 Mainboard
Seagate Barracuda 40GB UDMA 100 HD

Compiler flags are "-march=athlon-tbird -O2 -pipe" so packages won't get 
too optimized. :)

I'm really looking forward to get things fixed.

i had this problem too once (and i have like 1.8gig p4 with 768 meg ram,  
etc...)  
  
it ended up being the fault of my kernel ... i created a new one with minimum  
options to compile and that one worked fine ...  
  
i was also using a vanilla kernel i grabbed from kernel.org, so its probably  
not a Gentoo thing ... 
 
could you try the samething ?  build a kernel from vanilla sources, only enable 
the options which would allow you to boot the system and compile something ... 
no X, no sound, no cdburner, none of that stuff ... 

Thanks,
I'll give it a try after I've played around a bit with some windowmanagers 
(today's windowmanagers day ;)).
I've used vanilla-sources and patched preempt and grsecurity against them. My 
kernel is very small in size (I usually build it with modules I really need).
Perhaps preempt is my kernel's "enfant terrible". :)

Ok, built a new minimal kernel without extra patches and all that stuff.
Same problem: the compilation of kdelibs starts and at some point freezes the
system. It's not very slow, it's really frozen. ;) A few moments ago I tried to build it
right under a terminal (to avoid that other programs could possibly envoke
conflicts with compilation), same results. Right now I'm building xfree-4.2.1 and it's
working nice; guess it's got something to do with either g++ or the kdelibs/kdebase ebuilds
itself..

I guess it had something to do with my hardware..perhaps overheating of some
specific components. After putting a ventilator next to my box everything worked fine..perhaps I should buy a few more fans. ;)
Closing bug.
