[swift-dev] build-script -x freezing?

[Will Stanton]

Hi Geoffrey,

Wanted to share I encountered this issue on 5/11.
(Ninja build was+is fine.)

Maybe the first 8 gyb scripts to run (I’m on a 2012 Mac Mini) are not recognized as having finished…
As you suggest, CPU of xcodebuild, cmake, and python processes were all 0.

Regards,
Will Stanton
