GDB5 TOT on unixware 7

[Robert Lipe <robertl at sco dot com>]

I just spun the top of tree of the GDB5 branch on UnixWare 7.  As a
practical matter, the current thread support is somewhat more annoying
than when GDB was thread-unaware.


This GDB was configured as "i586-sco-sysv5uw7.1.1"...
(gdb) run
Starting program: /home/robertl/src/tmp/udiproto.timer/env/posix/./timertest 
[New LWP 1]
[New Thread 1]
[New Thread 2]
[New Thread 3]
[New Thread 4]
[New LWP 2]
[Exited Thread 2]
[LWP 2 exited]
[New LWP 3]
procfs: fetch_registers, get_gregs line 3514, /proc/10235/lwp/2: No such file or directory.
[Switching to LWP 2]
procfs: fetch_registers, get_gregs line 3514, /proc/10235/lwp/2: No such file or directory.
(gdb) c
Continuing.
procfs: fetch_registers, get_gregs line 3514, /proc/10235/lwp/2: No such file or directory.

Note that at this point, it's trying to switch to an LWP that it knows
has exited.  The results are not good. But what happens next is even
more annoying becuase now you're stuck in GDB and have to job control it
and kill it.


(gdb) q
The program is running.  Exit anyway? (y or n) y
procfs: couldn't find pid 10235 in procinfo list.

Nick, can you spot a ready fix for this? 

Thanx,
