Later it gets resolved into both C::C() and C::C(int) which crashes GDB: breakpoint.c:9641: internal-error: breakpoint_re_set_one: Assertion `sals.nelts == 1' failed. It is the same problem as existing: FAIL: gdb.objc/objcdecode.exp: continue after break on multiply defined symbol (GDB internal error) but this testcase is not dependent on objc (only on C++). static int breakpoint_re_set_one (void *bint) if (!not_found) { --> gdb_assert (sals.nelts == 1); I ask now only for a testcase check-in. Proposing for a later fix just to completely disable the unqualified names resolution for C++. C::C would autocomplete it to C::C() if there are no other choices.
