Bug 21310 – Itanium C++ mangler handling templated multiple pointer arguments with different type qualifiers incorrectly

Incorrect mangling for templated function with multiple pointer arguments with different type qualifiers. ---- extern(C++) void func(T)(const(T*) a, T* b); void main() { int i = 0; int* pi = &i; func(&i, pi); } ---- This is mangled to _Z4funcIiEvPKT_S1_ with the dmd Itanium C++ mangler implementation, whereas g++ gets _Z4funcIiEvPKT_PS0_ Issue seems to be in checking for substitution of args 2 onwards, where it finds a match between const(T*) and T*. Not an issue for non-templated functions.
