There is no workaround, there is a compiler bug that can be triggered with very simple code. The compiler bug is said to be fixed in 2015 update 3, release date unknown. (and I'm afraid update 3 will contain the new optimizer that has been announced a couple weeks ago, which can have its own collection of new bugs) Mike _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
