[Mono-list] mono debugger

[Jonathan Gagnon]

Hi,
 
I have a core dump of mono that I generated with gcore.  I want to be able
to see the managed call stack of the diffrent threads.  With the information
I got from here :
 
http://www.mono-project.com/Debugging
 
I thought I'd be able to see it with the mono_stack macro.  Unfortunately,
it requires a running application and it doesn't work with a core dump (I
get the error message "You can't do that without a process to debug." from
gdb).
 
I then tried the mono debugger.  According to the features list found here
(http://www.mono-project.com/Debugger), it is supposed to be able to examine
core dumps.  Unfortunately, I can't find the documentation on how to do it
anywhere.  The only thing I found out is that I can use the command "core
coreFileName" to load the core dump, but I get an exception when I do this.
Here is the exception I get :
 
(mdb) core ./core.27349
Loading core file ./core.27349
ERROR: Caught exception while executing command
Mono.Debugger.Frontend.DebuggerEngine: System.EntryPointNotFoundException:

Is this supposed to work and if it is, how can I get it to work?
 
Otherwise, is there any other way that I could get the managed call stack of
the threads from a core dump?
 
Thanks,
 
Jonathan
