# This file is a regression test for PR42399, where timing variations can
# cause test names to be truncated under certain conditions.
# The bug was originally reported using a C test case, but GNU Awk is
# sufficiently fast for a simple Awk script to also trigger the bug.
# The bug was originally reported as only affecting long test names, but
# the underlying issue applies equally to shorter names, as long as the
# unit test program produces output faster than DejaGnu can read it.
