Summary: [4.7 Regression] Debug-mode forward_list broken
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: paolo.carlini@oracle.com
Something changed either in the front-end or the middle end over the next
couple of days which broke the debug-mode forward_list, like this:
...debug/forward_list:650:25: error: request for member
‘__gnu_debug::_Safe_iterator_base::_M_prior’ in ‘__rhs_iterators->’, which is
of non-class type ‘__gnu_debug::_Safe_iterator_base*’
To reproduce just compile, with -std=c++0x -D_GLIBCXX_DEBUG:
////////////
#include <forward_list>
////////////
No recent changes to the library itself can possibly have caused this.
HJ, can you search the offending patch?

Tried Rev 174498 and was Ok. Could be 174499.

It seems unfortunate that make check-libstdc++-v3 doesn't catch obvious
breakage like this; at the least we could make sure that stdc++.h compiles in
debug/parallel modes?

Yes. Running by default the entire testsuite in debug-mode too is not an
option, would take too much time. Honestly, however, in my experience, isn't
*that* common that a front-end issue shows up *only* in debug-mode and, anyway,
the library developers proper run check-debug too rather often and are willing
to file PRs ;) Thanks for the quick fix!
