            Bug ID: 78467
           Summary: [7 regression] gcc.dg/tree-prof/comp-goto-1.c FAILs
           Product: gcc

            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---
              Host: sparc-sun-solaris2.12

Between 20161117 and 20161121, gcc.dg/tree-prof/comp-goto-1.c started to FAIL
on
32-bit SPARC:

+FAIL: gcc.dg/tree-prof/comp-goto-1.c execution,    -fprofile-generate
-D_PROFIL
E_GENERATE
+UNRESOLVED: gcc.dg/tree-prof/comp-goto-1.c compilation,  -fprofile-use

+UNRESOLVED: gcc.dg/tree-prof/comp-goto-1.c execution,    -fprofile-use

The -fprofile-generate execution SEGVs and even gdb aborts when trying to
investigate.  dbx is at least able to get a stack trace:

signal SEGV (no mapping at the fault address) in (unknown) at 0x51cdc
0x00051cdc:     <bad address 0x00051cdc>
Current function is main
  158     res = simulator_kernel (2 + 1, &env);
(dbx) where
  [1] 0x51cdc(0x2, 0x11dac, 0x258d8, 0x3fff, 0x0, 0x8), at 0x51cdc 
=>[2] main(), line 158 in "comp-goto-1.c"
