* [Bug c++/53845] New: Another "error reporting routines re-entered" issue @ 2012-07-03 19:58 jewillco at osl dot iu.edu 2012-07-03 21:44 ` [Bug c++/53845] " paolo.carlini at oracle dot com ` (5 more replies) 0 siblings, 6 replies; 7+ messages in thread From: jewillco at osl dot iu.edu @ 2012-07-03 19:58 UTC (permalink / raw) To: gcc-bugs http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53845 Bug #: 53845 Summary: Another "error reporting routines re-entered" issue Classification: Unclassified Product: gcc Version: 4.7.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned@gcc.gnu.org ReportedBy: jewillco@osl.iu.edu This example causes "Error reporting routines re-entered", and seems to be different from those reported so far: struct a {}; template<typename> struct b; template<> struct b<a> {static const int v = 3;}; template <typename L> struct c { static_assert(b<L>::v == 3, ""); using t = int; }; template <typename E, typename T> auto d(T x) -> decltype(((x.template e<E>()))) {return ((x.template e<E>()));} template <typename B> struct f { template <typename E> struct h { using w = int; typename c<E>::t x; }; template <typename E> decltype(d<typename h<E>::w>(*(B*)nullptr)) e(); }; struct g { template <typename> int e(); }; int main(int argc, char** argv) { d<a>(f<g>{}); return 0; } It is probably invalid code. Some small variations on it cause infinite loops (recursion depth exceeded), which also seem to be incorrect. The full error message for the code above with 4.7.1 is: ‘ Internal compiler error: Error reporting routines re-entered. Please submit a full bug report, with preprocessed source if appropriate.

Similar ICE can also be triggered in many cases with -fdump-tree-all option. The dumper tries to print template parameters which triggers template instantiation (odd). The instantiation may fail for unknown reason causing the ICE. David ^ permalink raw reply [flat|nested] 7+ messages in thread
