Bug ID: 64035
   Summary: [C++11] ICE in reshape_init_r when using initializer
list aggregate initialization for default function
parameters
   Product: gcc
   Version: 4.9.2
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: c++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: mail at jonasplatte dot de

Test case (not using preprocessor directives, so not precompiled)

gcc -v:

Using built-in specs.

Thread model: posix
gcc version 4.9.2 (GCC) 

My system is a x86_64 arch linux, with linux 3.17.3-1-ARCH.

Compiler invocation for the test case:

g++ -std=c++11 test2.cpp -Wall -Wextra

The exact error message I get (also added it to the test case as comment):

test1.cpp:21:7: internal compiler error: in reshape_init_r, at
cp/decl.c:5481

I tried changing -std to c++14 and adding -pedantic to see if they make a
difference, which both don't.

(In reply to Richard Biener from comment #2)
> But 4.7 rejects it so there is no version that works.  How's it a regression?

Does the bug report imply this is a regression? If so, that was not
intentional.

EDIT: Sorry for the noise, I didn't notice the summary change before.

Jonas Platte  changed:

   What|Removed |Added

Version|4.9.2   |5.2.0
  Known to fail||5.2.0

--- Comment #5 from Jonas Platte  ---
Still makes the compiler crash in 5.2.0 with pretty much the same error
message.

With decent experience in C++, but no experience working on GCC (or any other
compiler), could I help fixing this?
