            Bug ID: 57490
           Summary: ICE on c-c++-common/cilk-plus/AN/an-if.c
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ebotcazou at gcc dot gnu.org
            Target: sparc*-sun-solaris2.*

The test triggers an ICE with any options:

--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
As of 2013-06-14 (r200089), I see the following ICE on both Solaris/SPARC and
Solaris/x86, can be reproduced with x86_64-unknown-linux-gnu x
i386-pc-solaris2.10 cross compiler:

Preprocessed testcase attached.

Balaji, could you please have a look.  At least on Solaris/x86, this is the
last
remaining cilkplus testsuite failure (Solaris/SPARC bootstrap still running).
