Bug ID: 58824 Summary: Lambda trigger internal compiler error Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: thomas.sanchz at gmail dot com Created attachment 31058 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=31058&action=edit Source file + ii + s Hi, Please see in attached file the source triggering an internal error in gcc. The source file is compiled like this: $> g++ -std=c++11 -W -Wall -Wextra test.cpp test.cpp: In instantiation of ‘struct test<dummy>::__lambda0’: test.cpp:5:8: required from here test.cpp:8:20: internal compiler error: in tsubst_copy, at cp/pt.c:12116 { "test", [this]{} } The bug is triggered when `this` is captured from a template class and the lambda is assigned directly from the class definition. The platform tested is an ubuntu 13.10 with default shipped compiler: $gcc -v Using built-in specs.
