[Bug general/4347] New: LinuxPtraceTask aborts when trying to activate a new Proc from Source Window

[rmoseley at redhat dot com]

When calling the "Manager.host.requestCreateAttachedProc(cmd, new
AttachedObserver());" method from the SourceWindowFactory the Linux core
generates an unhandled exception error as follows:

{frysk.proc.LinuxPtraceTask@12f60e0,pid=9905,tid=9905,state=StartMainTask.wantToAttachContinue}
in state "StartMainTask.wantToAttachContinue" did not handle handleTerminatedEvent

java.lang.RuntimeException:
{frysk.proc.LinuxPtraceTask@12f60e0,pid=9905,tid=9905,state=StartMainTask.wantToAttachContinue}
in state "StartMainTask.wantToAttachContinue" did not handle handleTerminatedEvent

This was actually a problem with the GUI passing a file path to execvp with a
space on the front of it.

The core shouldn't panic when the exec path is invalid though :-)

Still seeing this randomly.  Here is another stacktrace:

{frysk.proc.LinuxPtraceTask@1143e00,pid=32052,tid=32052,state=detached} in state
"detached" did not handle handleTerminatedEvent

java.lang.RuntimeException:

   at java.lang.Thread.run(libgcj.so.7)

This pops up *sometimes* shorty after a source window has been brought up that
has been attached to a running bash process.

I can no longer reproduce this.  It appears to be fixed.
