No, it should not be a WONTFIX. The DSE implementation should try not to
delete part of prologue/epilogue .

This is now fixed with the new DSE on the trunk which came in with the dataflow
merge (which was really a rewrite of flow.c :) )

Simplified testcase. This bug is probably a WONTFIX.
int bar (int *);
int foo (void)
{
int x;
__builtin_memset (&x, 0, 32);
return bar (&x);
}
