Package: expect
Version: 5.45.4-7
Severity: normal

Dear Maintainer,
* What led up to the situation?
I ran the gdb testsuite on a ppc64-linux machine, and ran into a failure in
a test-case. For more details, see
https://sourceware.org/bugzilla/show_bug.cgi?id=34471. I manage to minimize
the behaviour to a standalone expect script:
...
$ cat test.exp
exp_internal 1
set str "all"
set re {(?=a)all}
# Matches here:
puts [regexp $re $str]
spawn sh -c "cat <<'EOF'
$str
EOF"
# But not here:
expect {
-re $re {
puts "PASS"
}
}
...
* What exactly did you do (or not do) that was effective (or
ineffective)?
I ran the script:
...
$ expect test.exp
1
spawn sh -c cat <<'EOF'
all
EOF
parent: waiting for sync byte
parent: telling child to go ahead
parent: now unsynchronized from child
spawn: returns {2779718}
Gate keeper glob pattern for '(?=a)all' is 'aall'. Activating booster.
expect: does "" (spawn_id exp4) match regular expression "(?=a)all"? Gate
"aall"? gate=no
all
expect: does "all\r\n" (spawn_id exp4) match regular expression "(?=a)all"?
Gate "aall"? gate=no
expect: read eof
expect: set expect_out(spawn_id) "exp4"
expect: set expect_out(buffer) "all\r\n"
...
* What was the outcome of this action?
- Gate keeper glob pattern for '(?=a)all' is 'aall'.
- no PASS in the output
* What outcome did you expect instead?
- Gate keeper glob pattern for '(?=a)all' is 'all'.
- PASS in the output
