The pattern has (\n|\r\n|\r).I am not exactly sure what you mean but when I run the test by itself from the command and redirect the output to a file, this is what the output looks like: 0000000 2031 2032 3320 0a0d 2031 2032 3320 0a0d 0000000 1 2 3 \r \n 1 2 3 \r \n 0000010 0a0d 2a2a 202a 5845 5449 6320 646f 2065 0000010 \r \n * * * E X I T c o d e 0000020 0d30 000a 0000020 0 \r \n 0000023 It looks like we have \r\n at the end of each line. Is it possible it is not CR/LF but the EXIT code message confusing the pattern?
Contrary to Andreas, I do see \r in run.txt – at least when I look at the file when saved from Thunderbird. Namely, the output is (sp = space, nl = \n, cr = \r):
1 sp 2 sp sp 3 cr cr nl 1 sp 2 sp sp 3 cr cr nl cr cr nl *** EXIT code 0 cr cr nlNamely: I do not see CR-NL but CR-CR-NL. That looks rather odd and does not match what you get when you manually run the program. Looing at other lines like "spawn sis -i ./f77-edit-x-out.exe", they have a CR-NL, i.e. only a single CR. Thus, the question is what inserts an additional "\r" into the output.
Additionally, I think you are right that the "*** EXIT code 0" also causes problems with the pattern. Can you try the following:
a) Replace the pattern by "1 2 3(\n|\r\r\n|\r)" (twice), note the duplicated "\r"
b) Remove the "dg-output "\$" line[Best would be if you could try them also separately.] My bet would be that doing (a) and (b) will succeed, while only (a) and (b) will fail.
If using (a) [alone or together with (b)] works, you should really find out what inserts the "\r", especially as it does not appear if you manually run the program. "\r\r\n" is definitely not a pattern I would like to see in the test file.
If (b) works [alone or together with (a)]: Any chance that you silence the "\r\r\n*** EXIT code 0\r\r\n" output? I think it could potentially confuse other test cases and it doesn't belong there. – I am also inclined not to remove the '\$', unless there are very compelling reasons to do so.
