           Summary: attach to multithreaded process does not show threads in
                    Frame Stack
           Product: kdevelop
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: debugger
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: halls at debian.org


Version:           unknown (using KDE 3.1.4)
Installed from:     (testing/unstable)
Compiler:          gcc version 3.3.2 20030908 (Debian prerelease)
OS:          Linux (i686) release 2.4.22-1-686-smp

Attaching to an existing program with multiple threads only shows one thread in the Frame Stack.  This is because 'info threads' can only be requested from gdb after the 'backtrace' command 

(gdb) attach 19622 

[previous behaviour requests info thread here.. threads not shown yet]

(gdb) backtrace 
[New Thread 16384 (LWP 19622)]
[New Thread 32769 (LWP 19623)]
[New Thread 16386 (LWP 19624)]
[New Thread 32771 (LWP 19625)]
...

[now we can request info thread.]
