Bug ID: 65392
Summary: Bad mangled names in Debug Mode assertions
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
#include <deque>
int main()
{
std::deque<int> d;
auto it = d.begin();
it - 2;
}
/usr/include/c++/4.8.3/debug/safe_iterator.h:378:error: attempt to retreat
a past-the-end iterator 2 steps, which falls outside its valid range.
Objects involved in the operation:
iterator @ 0x0x7fff3e6b1930 {
type =
N11__gnu_debug14_Safe_iteratorINSt9__cxx199815_Deque_iteratorIiRiPiEENSt7__debug5dequeIiSaIiEEEEE
(mutable iterator);
state = past-the-end;
references sequence with type `NSt7__debug5dequeIiSaIiEEE' @ 0x0x7fff3e6b1930
}
Aborted (core dumped)
The types shown are not valid symbol names and cannot be demangled. They are
missing the _Z prefix.
We should not bother printing out mangled names if users can't demangle them to
get something meaningful. Ideally we should be demangling them automatically.

Symbols are now automatically demangle, the issue doesn't appear anymore.

--- Comment #11 from vries at gcc dot gnu.org ---
The ipa-pta solution no longer works. In 4.6, we had:
...
# USE = anything
# CLB = anything
GOMP_parallel_startD.1048 (main._omp_fn.0D.1472, &.omp_data_o.1D.1484, 0);
# USE = anything
# CLB = anything
main._omp_fn.0D.1472 (&.omp_data_o.1D.1484);
# USE = anything
# CLB = anything
GOMP_parallel_endD.1049 ();
...
On trunk, we have now:
...
# USE = anything
# CLB = anything
GOMP_parallelD.1345 (main._omp_fn.0D.1844, &.omp_data_o.1D.1856, 0, 0);
...
So there's no longer a path in the call graph from main to main._omp_fn.
Perhaps a dummy body for GOMP_parallel could fix that.
