Bug 19713 – dmd crashes generating code for C++ template function

This code compiles fine: -------------------------- extern(C++) { double twice(double d) { return d * 2; } void* createFunction(double function(double)); } void main() { const f = createFunction(&twice); } ------------------------------ This crashes dmd 2.084.0: -------------------------- extern(C++) { double twice(double d) { return d * 2; } void* createFunction(R)(R function(double)); } void main() { const f = createFunction(&twice); } ------------------------------ It doesn't crash with `dmd -o-` suggesting it's in the code generation. It also doesn't crash if `extern(C++)` is removed.
