Problem with scan-tree-dump-times in dg.exp

[Diego Novillo]

I have a new test case where the dump file ought to have 2
occurrences of the pattern "PREDICATE: p.* ne_expr 0B", so I
added

/* { dg-final { scan-tree-dump-times "PREDICATE: p.* ne_expr 0B" 2 "vrp" } } */

but I'm getting a dump scan failure on that file.  I have
manually checked the dump file and there are 2 instances of
that pattern:

$ grep 'PREDICATE: p.* ne_expr 0B' vrp07.c.t23.vrp
        PREDICATE: p_5 ne_expr 0B
        PREDICATE: p_5 ne_expr 0B

I can't seem to find other test cases with similar patterns.  And
the verbose flags don't show anything obvious.


Thanks.  Diego.
