Build fails with "internal compiler error" on gcc-4.7 #52

Closed Wallacoloo closed 9 years ago

Wallacoloo commented 9 years ago

Something changed in https://github.com/Wallacoloo/printipi/commit/08bb9ee9ed28198f7b3ec93460327b13336b6b1d causes an internal compiler error in gcc-4.7 when using link-time optimization (on x86-64). The bug isn't present on gcc-4.8 or 4.9, and also absent on 4.7 with lto disabled.

Deleting the livingPin set in IoPin fixes the error. Specifically, deleting the line static bool registeredWithSched = false; in the templated IoPin constructor removed the error (but changed the functionality, of course).
