             Bug #: 52463
           Summary: libitm.c/memcpy-1.c FAILs
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end

              Host: i386-pc-solaris2.1[01], sparc-sun-solaris2.11
            Target: i386-pc-solaris2.1[01], sparc-sun-solaris2.11
             Build: i386-pc-solaris2.1[01], sparc-sun-solaris2.11


Since 20120301, libitm.c/memcpy-1.c started to FAIL on Solaris/x86 and SPARC
in various ways:

* On 32-bit Solaris 10 and 11, SPARC and x86, the compilation never terminates:

WARNING: program timed out.
FAIL: libitm.c/memcpy-1.c (test for excess errors)
WARNING: libitm.c/memcpy-1.c compilation failed to produce executable

* On 64-bit Solaris 10/x86, I get an ICE:

FAIL: libitm.c/memcpy-1.c (internal compiler error)
FAIL: libitm.c/memcpy-1.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/libitm/testsuite/libitm.c/memcpy-1.c:93:5: internal
compiler error: Segmentation Fault

  The ICE vanishes with -v and/or -save-temps.

The problem is also present on the 4.7 branch.
