[ADMB Users] memory allocation error

[Derek Seiple]

If you are using gdb in the command line, then to put in a breakpoint you type

break <file>:<line>

so find where ad_exit() is in the code, say it is in ad_exit_file.cpp
at line 300 then you would say

break ad_exit_file.cpp:300

There are other ways but this is the easiest.

Once you run your program and it stops at your breakpoint type in 'bt'
without the quotes (bt for "backtrace"). That will give you a list of
functions: the function you are currently in, the function that called
the function you are in, the one that called that function, ... etc
back to main().

Hope that helps,

Derek
