http://d.puremagic.com/issues/show_bug.cgi?id=588 I was recently working on nested symbol support for std.demangle as well, and ran into a bug. Your version has that same bug: urxae ubuntu:~/tmp$ cat test.d int intfunc() { void inner() { } return 0; } class UDT {} UDT udtfunc() { void inner () { } return new UDT; } urxae ubuntu:~/tmp$ dmd -c test.d urxae ubuntu:~/tmp$ nm test.o | grep inner 00000000 T _D4test7intfuncFZi5innerFZv 00000000 T _D4test7udtfuncFZC4test3UDT5innerFZv urxae ubuntu:~/tmp$ nm test.o | grep inner | ./demangle 00000000 T int test.intfunc() . void inner() 00000000 T class test.UDT.inner test.udtfunc() . void function() (same effect for struct UDT & typedef UDT, IIRC) It's caused by an ambiguity in the mangling. It is caused by several factors: * Functions have their name first, and their return type last. * UDTs (structs, classes and typedefs) have a mangled name of multiple parts with no terminator. * Inner functions are mangled as <mangled outer function> ~ <inner function> * Inner function names (which comes directly after the mangled outer function) have the same syntax as one part of an UDT name. All of this causes the name of the inner function to be mistaken for the last part of the return type. The easiest fix would be for the mangling to change :). A simple terminator char after an UDT name would do it. --

I've been working a bit on std.demangle again, based on this patch and the latest version from Phobos. I've made these changes: * bit -> bool * Added support for 'M' attribute to functions (which indicates a 'this' or context pointer as last argument) --
