             Bug #: 51784
           Summary: [4.7 Regression] FAIL: gcc.dg/tree-prof/pr44777.c

          Priority: P3

At revision 182975 on x86_64-apple-darwin10, the test
gcc.dg/tree-prof/pr44777.c fails with a segmentation fault:

Program received signal SIGSEGV, Segmentation fault.
0x900949d9 in __findenv () from /usr/lib/libSystem.B.dylib
(gdb) bt
#0  0x900949d9 in __findenv () from /usr/lib/libSystem.B.dylib

#5  0x00001cc8 in main () at
/opt/gcc/work/gcc/testsuite/gcc.dg/tree-prof/pr44777.c:42

Although the test has been introduced at revision 182920, I have marked it as a
regression since there is no segmentation fault at revision 182587.
