I found that when a mangled name is very long, it turns into UNREADABLE characters. And the limit of the length is 128 characters.( It is too short! )

----- Beginning of source
module manglingtest;    // length of module name is significant!

class MyClass { }

void tfunc(T, U)(T a, U b) { }

void main() {
        auto a = new MyClass;
        auto b = new MyClass;
        tfunc(a,b);        // wrong mangling
}
----- End of source

(Additional) I am using a tool to read build messages and map files, so such unreadables are especially inconvenienced. And I want to write for profiler's output, too.

Environment:
D2.055
Windows XP SP3 32-bit

This is a limitation of the current linker. Until a linker comes around that can handle humongous names, this will not be fixed. Walter is in the process of rewriting the linker, so perhaps this will eventually be fixed, but don't hold your breath.

It'll have to wait until we move to a new object file format.
