Would it be possible to do some runs with parallel make disabled ? I'd like to determine if this is a task race, or a Makefile dependency race. 52603 2 ross.burton 2015-07-24 20:26:42 +0000 Occasionally, I've seen it on the AB twice and a few times locally. If I can replicate here I'll disable parallel builds. 52604 3 ross.burton 2015-07-24 20:32:52 +0000 Happened again in the world build: https://autobuilder.yoctoproject.org/main/builders/nightly-world/builds/409/steps/BuildImages/logs/stdio (I also note that it found lzma in that run) 52758 4 richard.purdie 2015-08-01 06:36:13 +0000 http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=741a44c06b1e53b641f2a5c48985a81e3c1e27cf
