[Bug testsuite/25241] DejaGNU does not distinguish between errors and warnings

["manu at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #30 from manu at gcc dot gnu dot org  2007-03-22 22:36 -------
There is yet another strange behaviour of the current patch. For the testcase
in gcc.dg/array-2.c:

struct g g1 = { { 0, { } } };
struct g g2 = { { 0, { 1 } } }; /* { dg-error "(nested context)|(near
initialization)" "nested" } */

struct h { int x[0]; int y; };
struct h h1 = { { 0 }, 1 }; /* { dg-error "(excess elements)|(near
initialization)" "before end" } */

The output is:
gcc.dg/array-2.c:10: error: initialization of flexible array member in a nested
context
gcc.dg/array-2.c:10: error: (near initialization for 'g2.f.x')
gcc.dg/array-2.c:13: warning: excess elements in array initializer
gcc.dg/array-2.c:13: warning: (near initialization for 'h1.x')

And the test fails as follows:

PASS: gcc.dg/array-2.c nested (test for errors, line 10)
PASS: gcc.dg/array-2.c before end (test for errors, line 13)
FAIL: gcc.dg/array-2.c (test for excess errors)
Excess errors:
/home/manuel/src/trunk/gcc/testsuite/gcc.dg/array-2.c:13: warning: excess
elements in array initializer

It seems that the second dg-error matched the wrong line. Perhaps it is getting
confused by the alternatives. No idea.
