--- Comment #15 from Nicholas Miell <nmi...@gmail.com> --- r600g initializes LLVM without first setting the llvm::DisablePrettyStackTrace variable to true. If this variable is false (the default), LLVM will register a bunch of signal handlers, including for SIGXCPU and SIGPWR, both of which are used by Mono's garbage collector. gallivm correctly sets llvm::DisablePrettyStackTrace to true, but it runs after r600g has already started calling into LLVM and the signal handlers have been registered. If you set a breakpoint on r600_create_context, manually set llvm::DisablePrettyStackTrace to true and then continue, the application will function correctly. I tested this using Fractal (a Unity game which deadlocks in sem_wait on startup), Bastion (a MonoGame, also deadlocks in sem_wait), and RepetierHost (an OpenTK app which dies in the SIGXCPU handler at startup). -- You are receiving this mail because: You are the assignee for the bug.
