Re: [bug-gawk] gawk/master doesn't print when profiling

[arnold]

After turning \n into \r in the attachment, I can reproduce this. I note
that without -p the 2nd version does work.

This is weird, since the byte code for all three is the same! (At least
according to the dump from the debugger.)

I will try to track it down.

Thanks for the report.
