Bugzilla Bug 18920

Trying to build qt on a 1.4 system always fails as follows:

I am using -march=pentium -O3 -pipe.  -march=pentium-mmx fails with a different
ASM-related error.  The error occurs both with and without distcc.  The distcc
peer is a Duron 1400 Gentoo 1.4RC3 box with 1024MB RAM.

The system is a Pentium 200/MMX with 128MB RAM and a 256MB swap.

Reproducible: Always
Steps to Reproduce:
1. emerge qt

Actual Results:  
The build progresses to the designer build, then fails.

this problems can be caused by hardware stress (overclock and all heat-related
issue),  
i would also suggest you to use MAKEOPTS="-j2" or -j1 and try again emerging qt
