[DTrace-devel] [PATCH] test: Suppress some white space

[eugene.loh at oracle.com]

From: Eugene Loh <eugene.loh at oracle.com>

The test suite turns pointers into "{ptr}" so that results
comparisons will not be sensitive to particular pointer offset
values.

If these offsets change in width -- say, from 0xf0 to 0x100 --
the amount of white space in the postprocessed output can change.

Add additional postprocessing to a test that sometimes fails due
to this problem.
