Stupid question, but are C++ exceptions working for you? I think we don't change anything inthe compiler related to exception handling, so if C++ worked and D didn't it could only be a problem with the runtime
code?


I investigated this a little. It seems that the processor gets a fault interrupt when calling _Unwind_RaiseException in _d_throw. The status bits indicate an invalid instruction code. When looking at the disassembly I see that the call is a blx instruction with address. In Cortex-m4 blx can only take a register argument.
Is this a bug in gdc or gcc?
