I had to resort to nuking my build directory in order to get a working build. It seems like something in the offlineasm world isn't rebuilding the necessary bits? 1009409 1 simon.fraser 2014-05-14 19:40:06 -0700 This interrupts about every 3rd build that I do. 1009410 2 fpizlo 2014-05-14 19:40:53 -0700 (In reply to comment #1) > This interrupts about every 3rd build that I do. Do you do anything between those three builds, other than WebCore changes? 1009411 3 simon.fraser 2014-05-14 19:42:08 -0700 I'm flipping between branches, between architectures and between targets (iOS/OS X).
