I just saw WebKitGTK+ 2.6.1 failing to build in ppc64el:

[  2%] Generating ../../DerivedSources/JavaScriptCore/LLIntDesiredOffsets.h

Comment 1 Alberto Garcia 2014-10-14 05:35:36 PDT 
It built fine after a second try. I haven't taken a look at this yet, but I guess this might be some sort of race condition?
Comment 2 Alberto Garcia 2014-10-28 05:23:08 PDT 
We haven't been able to reproduce it again after many attempts in different architectures, it was probably fixed in 2.6.2, I'll close this.
