[Pharo-project] Providing a Cog debug [WAS] Fwd: [Vm-dev] Debugging Cog crash

Hi...I was reading this thread, and even before his last answer, I was
thinking more or less the same. Is it worth it to create one more target in
Hudson so that to create cogs but with debug flags?

It is not necessary to create for stack vm, cog and mt. Maybe just cog is
enough. And one for each OS. So, it is only 3 targets, using:
CogDebugMacOSConfig, CogDebugUnixConfig, and ... (sorry, I didn't find in
windows..).

What do you think? is it worth it ? or we can say "ehhh ehh compile it by
your own " ?

cheers

Mariano

Is there a debug version of Cog that I can run on the box?  I have casually
avoided learning how to build Cog in part because that means I can't hack
the FFI plugin, which forces me to play by the rules on library
paths/ldconfig, etc.  It also means that I don't have a build environment
ready to go, so I can't readily add syslog() calls to bracket where it
quits.  gdb isn't helping as described below.

If there is something you want me to try, let me know.  We have a
reproducible Cog crash.

Levente,

I follow on why my shell script did not work.  Your instructions got me
going, but we still don't have an answer.  The vm is running, but I cannot
attach:

>From what I read, one answer is the get the image loaded and then attach -
my problem is that the vm never gets far enough to actually load the image.

Any ideas?

Bill
