GDB should be able to resolve the typedef in the user expression and find the correct member. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 3+ messages in thread

I think part of the problem is that the typedef is omitted from the debuginfo? Locally: (gdb) ptype tbase No symbol "tbase" in current context.
