Bug 514960 – MAKEOPTS=-j65 does not work with 2 processors and 2 gigabytes RAM

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description tharvik 2014-06-24 20:40:21 UTC]

dev-libs/boost-1.52.0-r6 fail with MAKEOPTS=-jN with N > 64. 64 was choose based on trials and errors, and is given as a lower bound.

Reproducible: Always

Steps to Reproduce:
1. MAKEOPTS=-j65 emerge '=dev-libs/boost-1.52.0-r6'
Actual Results:  
/var/tmp/portage/dev-libs/boost-1.52.0-r6/temp/environment: line 1015: 24967 Segmentation fault      b2 "$@"

Expected Results:  
Emerge correctly.

As it may not be a common situation, it easily happend if you have a MAKEOPTS base on load as MAKEOPTS="-j -l4".

You have two gigabytes of memory and what looks like two processors, and no distcc, and you are surprised you ran out of RAM?

Nope, not resolved, tested on 4 cpu and 4G (and max memory usage ~100MB).
