Why is dejagnu skipping some tests in the testsuite?

[Johannes Pfau]

cat gcc/testsuite/gdc/gdc.sum | grep template6.d
PASS: runnable/template6.d (test for excess errors)
PASS: runnable/template6.d execution test
PASS: runnable/template6.d -g  (test for excess errors)
PASS: runnable/template6.d -g  execution test
PASS: runnable/template6.d -O2  (test for excess errors)
PASS: runnable/template6.d -O2  execution test
PASS: runnable/template6.d -g -O2  (test for excess errors)
PASS: runnable/template6.d -g -O2  execution test
PASS: runnable/template6.d -frelease  (test for excess errors)
PASS: runnable/template6.d -frelease  execution test
PASS: runnable/template6.d -g -frelease  (test for excess errors)
PASS: runnable/template6.d -g -frelease  execution test
PASS: runnable/template6.d -O2 -frelease  (test for excess errors)
PASS: runnable/template6.d -O2 -frelease  execution test
PASS: runnable/template6.d -g -O2 -frelease  (test for excess errors)
PASS: runnable/template6.d -g -O2 -frelease  execution test

but:

cat gcc/testsuite/gdc/gdc.sum | grep testenum.d
PASS: runnable/testenum.d (test for excess errors)
PASS: runnable/testenum.d execution test

@Iain do you know why this is happening?



This was hiding yet another problem:

gdc -g runnable/testenum.d
