Hi!
I just checked out this regression but I think there's something odd
going on in the setup that is running the tests. When I run the test
locally, the relevant part of the logs looks like this:
(gdb) PASS: gdb.threads/threadcrash.exp: test_live_inferior:
continue to breakpoint: running to breakpoint
print $_inferior_thread_count^M
$1 = 7^M
(gdb) PASS: gdb.threads/threadcrash.exp: test_live_inferior:
$thread_count == 7
thread apply all backtrace^M
^M
< lots of GDB output >
(gdb) PASS: gdb.threads/threadcrash.exp: test_live_inferior: Get
thread information
PASS: gdb.threads/threadcrash.exp: test_live_inferior: $unwind_fail
== false
PASS: gdb.threads/threadcrash.exp: test_live_inferior:
$thread_count == [llength $test_list]
Whereas the failed log reads like this:
(gdb) PASS: gdb.threads/threadcrash.exp: test_live_inferior:
continue to breakpoint: running to breakpoint
print $_inferior_thread_count
$1 = 7PASS: gdb.threads/threadcrash.exp: test_live_inferior:
$thread_count == 7
(gdb) PASS: gdb.threads/threadcrash.exp: test_live_inferior: Get
thread information
PASS: gdb.threads/threadcrash.exp: test_live_inferior: $unwind_fail
== false
FAIL: gdb.threads/threadcrash.exp: test_live_inferior:
$thread_count == [llength $test_list]
thread apply all backtrace
Notice how the gdb command to "apply all backtrace", which is used to
create the test_list variable, happens after checking if the variable
has been set correctly.
I have no clue how things can get so out of sync...
