Bug 369427 – app-emulation/qemu-kvm-0.14.1 can not compile with gcc-4.5.2

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Alex 2011-05-31 05:45:16 UTC]

while compiling gcc process allocates all the memory (2GiB of ram and 1 GiB of swap partition) htop shows that all memory is used by two gcc processes, but i compile in one thread. 
System hangs up because of swapping and i just abort the process.

Reproducible: Always

[Comment 3 Alex 2011-05-31 06:03:26 UTC]

it compiles successfully by gcc-4.4.5

[Comment 4 Søren Dalby Larsen 2011-05-31 07:38:33 UTC]

I've built it successfully with gcc 4.5.2 but had to change the CFLAGS to "-O1 -march=native" from my usual "-O2 -march=native -pipe". Could you try that?

[Comment 5 Doug Goldstein (RETIRED) 2011-05-31 15:50:50 UTC]

Using gcc 4.5.x the translate.o takes about 3GB from what I've seen. It takes significantly less with gcc 4.4.x. Not something we're going to fix in qemu's sources as the code does compile correctly, unless of course the toolchain guys can come up with a specific culprit.

[Comment 6 Alex 2011-06-01 03:31:17 UTC]

Yes, i have successfully compiled qemu-kvm on 4.5 with -O1 too, but gcc was allocate ~2GiB of memory.

[Comment 7 Sipingal Liu 2011-06-01 15:57:06 UTC]

same here(gcc-4.5.2 with 2G RAM), the compiling process is always killed by oom-killer.

[Comment 8 Märt Bakhoff 2011-06-02 22:12:47 UTC]

duplicate of bug 355861?
