Summary: internal compiler error: tree check: expected tree that contains ‘decl minimal’ structure, have ‘nop_expr’ in decl_linkage, at cp/tree.c:2975 Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: 1ze...@gmail.com Created attachment 22822 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22822 testcase I (unsuccessfully) tried passing a lambda as a template-parameter and resorted to reinterpret_casting it to a normal function-pointer, which caused an internal compiler error and gcc telling me to report it. $ gcc -v --save-temps -std=c++0x test.cpp Using built-in specs.

See <http://gcc.gnu.org/bugs.html> for instructions. I've attached test.cpp, which is very short and has almost the same contents as test.ii anyways.
