when I set PORTAGE_NICENESS = 15 or 5 at /etc/make.conf, some program compilation with emerge will abort showing this message... file.c:line: error: stray '\127' in program It doesn't happen at the same line every compilation, It has some random component. Unsetting PORTAGE_NICENESS fix the problem Reproducible: Sometimes Steps to Reproduce: 1./etc/make.conf: Set PORTAGE_NICENESS=15 2.emerge mplayer (or gimp or gcc or any big package) 3.

most likely bad hardware/kernel i think
An error on dimm memory block. Memtest detects the error after five minutes. However, I can't find any reason to explain why only niced emerge was affected by ram error.
