           Summary: libgo assertion failure at runtime/mem.c:114 on 64-bit
                    Solaris 10
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
        AssignedTo: i...@airs.com
        ReportedBy: r...@gcc.gnu.org
              Host: *-*-solaris2.10
            Target: *-*-solaris2.10
             Build: *-*-solaris2.10


Unlike Solaris 11/x86, several go and libgo tests fail on 64-bit Solaris 10
(both
SPARC and x86):

FAIL: go.go-torture/execute/array-1.go execution,  -O0 
/vol/gcc/src/hg/trunk/local/libgo/runtime/mem.c:114: libgo assertion failure
runtime: address space conflict: map(f840000000) = fffffb7ffbb7e000

I suppose this is because Solaris < 11 doesn't honor the addr parameter to
mmap(2) without MAP_FIXED (cf. gcc/config/host-solaris.c), but haven't yet
checked in detail.
