* [Bug c++/47068] New: [C++0x] internal compiler error on decltype(~ expression) @ 2010-12-27 16:20 spillner at acm dot org 2010-12-27 16:26 ` [Bug c++/47068] " paolo.carlini at oracle dot com ` (4 more replies) 0 siblings, 5 replies; 6+ messages in thread From: spillner at acm dot org @ 2010-12-27 16:20 UTC (permalink / raw) To: gcc-bugs http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47068 Summary: [C++0x] internal compiler error on decltype(~ expression) Product: gcc Version: 4.4.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned@gcc.gnu.org ReportedBy: spillner@acm.org The declaration template <class T> struct broken { int member; typedef decltype(~ member) gcc_crashes_here; }; generates the error message "internal compiler error: in lookup_member, at cp/search.c:1200, Please submit a full bug report" when compiled with g++ 4.4.3 (with -std=c++0x, naturally.) Similar code compiles without errors or warnings if any of the following transformations are applied: - A literal expression (e.g. "~ 0L") is substituted for "~ member" - The operators !, &, -, +, or * (when member is changed to a pointer type) are used instead of ~ - The struct is not templated - The typedef is declared in a free function (even a templated free function) rather than a class or struct - decltype is replaced by typeof and the code is compiled without -std=c++0x Unfortunately I'm traveling at the moment and can't easily test on other gcc versions. ^ permalink raw reply [flat|nested] 6+ messages in thread
