Bug ID: 61962
Summary: GCC seems to enter an infinite loop when compiling the
above code.
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: nick.tomlinson at arm dot com
Created attachment 33211

A minimal reproducer
==== Steps to reproduce ====
- Build with: g++ -fcilkplus -c arrayinf.cpp
- Wait for 60 seconds.
- Observe that g++ is still running.
==== What I expected to happen ====
- g++ should terminate, with an object file having been produces.
==== What actually happened ====
- After the 60 seconds, g++ is still running, and consuming an entire core.
==== Environment ====
I have tried this with:
- My system GCC (g++, version 4.9.1)
- A native build of GCC (${GCC_TRUNK}/bin/g++, revision r213234)
${GCC_TRUNK}/bin/g++ is a native build of GCC, with the following specified
to the configure script:
./configure --prefix=${GCC_TRUNK} \
--enable-languages=c,c++,fortran --disable-sjlj-exceptions
And make invoked as: make CXXFLAGS="-g3 -O0" -j9
$ uname -a

Also goes into a loop, though its reproducer is a lot longer, so its hard
to tell if it's for the same reason.
