Hi Elena and Keith,

I'm looking at some intermittent failures in gdb.mi/mi-threads.exp.
You fixed do_captured_list_thread_ids recently and I wonder if this
rings any bells for you.

I ran it 256 times on an unloaded system and collected the results.

My configuration is:

  target=native, host=i686-pc-linux-gnu, osversion=red-hat-8.0,
  gdb=HEAD%20021231, gcc=3.2.1, binutils=2.13.2, libc=vendor,
  gformat=dwarf-2

Two tests always FAIL:

  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 2
  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 7

These tests FAIL intermittently:

  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 3
  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 4
  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 5
  gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 6

There is a table at:

  http://www.shout.net/~mec/sunday/mi-pthreads/Non-PASS-gdb-HEAD.html

Does this ring any bells?  If not, that's fine, I'll throw it on the
giant heap of FAILs to analyze later.

Sure, here is the whole sections for mi-pthreads.exp from one gdb.log.

Hmmm, I see this:

  -thread-select 7
  ^done,new-thread-id="7",frame={level="0",addr="0x42028d69",func="sigsuspend",args=[],from="/lib/i686/libc.so.6"}
  (gdb) 
  FAIL: gdb.mi/mi-pthreads.exp: check_mi_thread_command_set: -thread-select 7

The test script wants to see:

  frame={.*},line=\"(-)?\[0-9\]+\",file=\".*\""

It looks like a test script problem rather than a gdb problem.

I'm using the vendor libc (without symbols).  Maybe you have a libc with
symbols?  Or maybe the frames are never in libc on your system.
