Bug #: 50861 Summary: ICE: internal compiler error: tree check: expected tree that contains ‘decl minimal’ structure, have ‘error_mark’ in tsubst_copy_and_build, at cp/pt.c:13526 Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: ca...@cs.stanford.edu Created attachment 25607 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25607 Program that causes g++ to ICE. g++ ICE's with error "internal compiler error: tree check: expected tree that contains ‘decl minimal’ structure, have ‘error_mark’ in tsubst_copy_and_build, at cp/pt.c:13526" Command to reproduce: /home/cas43/new-gcc/inst/bin/g++ prog.cpp -c -O3 Full diagnostic: prog.cpp:1:40: error: there are no arguments to ‘k’ that depend on a template parameter, so a declaration of ‘k’ must be available [-fpermissive] prog.cpp:1:40: note: (if you use ‘-fpermissive’, G++ will accept your code, but allowing the use of an undeclared name is deprecated) prog.cpp: In constructor ‘A<T>::A(int) [with T = int]’: prog.cpp:2:22: error: use of parameter from containing function prog.cpp:2:6: error: ‘int k’ declared here prog.cpp:2:22: error: ‘k’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive] prog.cpp:2:22: internal compiler error: tree check: expected tree that contains ‘decl minimal’ structure, have ‘error_mark’ in tsubst_copy_and_build, at cp/pt.c:13526 Please submit a full bug report, with preprocessed source if appropriate.
