Bug ID: 63584
Summary: ICE in strip_typedefs, at cp/tree.c:1326
Product: gcc
Version: 4.9.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jaredhoberock at gmail dot com
The attached preprocessed source produces the following compiler error message:
$ g++ -std=c++11 -pthread preprocessed_repro.cpp
â
In file included from test_nested_executor.cpp:3:0:
in strip_typedefs, at cp/tree.c:1326
auto inner_lambda = inner_lambda_gcc49_workaround<outer_index_type,
outer_shared_ref_type>{outer_idx, outer_shared_ref};
^
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.9/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccSYvoB9.out file, please attach this to
your bugreport.
I believe this is a regression because g++4.8.2-19ubuntu1 compiles the same
code which executes as expected.
