Hi Will, 

 

this was compiled using gcc, but even though the end of the output says the core was dumped, it only seems to produce a stackdump file, and gdb says that that is not a core dump file, and does nothing with it.  Do I have to change the compile or link flags to have it produce a core dump file?

 

Cheers

 

Ted

Anyway,  Hi Will,

 

Thanks, I would if I knew how to make sense of it.  Here is what is in the latest stackdump:

 

Exception: STATUS_ACCESS_VIOLATION at eip=6110D500

eax=20024D68 ebx=00000338 ecx=3FBBDE84 edx=20022070 esi=200223A8 edi=A9AE95F4

cs=0023 ds=002B es=002B fs=0053 gs=002B ss=002B

Stack trace:

Frame     Function  Args

      0 [main] test.pca.reg.gsl 7888 exception::handle: Error while dumping state (probably corrupted stack)

 

I look at it and I don't know what to make of what it is telling me.  How can I turn an of those values into something meaningful?

 

And the other one is even less intelligible:

 

Stack trace:

End of stack trace

 

How does one make sense of this?

 

I usually use gdb to help me see what's going on when I have a core file. I assume that since you mentioned gmake before you probably have gdb. If not, any system's normal debugger, like dbx, will make use of core files.

 

$ gdb prog-name core-name

 

Will load the core. The most useful command for me is "bt" ("where" under dbx), which shows you the call stack of the current thread.

 

Cheers,

Will
