This is a bit curious since I was under the impression that gdb demangled the linkage name, canonicalized it, and then used that name. So, barring cases where "physname" must be computed, I thought gdb wouldn't be using the name in the debuginfo. But, no big deal, some part of my understanding must be wrong. Probably a bug in the canonicalization code. -- You are receiving this mail because: You are on the CC list for the bug.
