Andrew,
The problem you encountered with fast responses seems to be related to
what I'd call the improper use of gdb_expect_list proc -- the proc is
fine, but one of the patterns in the pattern list needs to be adjusted
to work with expect.
In your original change, in the 2nd pattern, you need to remove the
trailing \[ \t\r\n\]+ RE. Otherwise, on a fast system expect will see
all the blanks / newlines leading to 0.000000 (part of the the 3rd
pattern), and consume these. When expect tries to match the 3rd
pattern, there's no leading blanks / newlines to match against!
I've tried your routine w/ a simple perl script acting as gdb (echos the
content below for print*, or just gdb prompt for anything else except
cont* which causes it to exit), and it works for me everytime after this
fix -- I think this experiment is good enough to emulate a fast
system :)
