[Insight-users] Segmentation fault

[Atwood, Robert C]

This brings to mind a couple of questions:

Do you have to rebuild the whole thing with the debugger flags ( -g or
similar?) or just the bits that are used by the application?=20

Would it work to link with Electric Fence (www.perens.com),  or dmalloc,
or other memory-allocation debugger library? Usually (in my own
programs) if the source of the fault is not immediately obvious, efence
allows it to be pinpointed quickly. (at HUGE memory cost) I haven't much
experience in c++ having used 'plain' c almost exclusively so I could be
out-to-lunch here.


Note: The latest ddd (3.3.9, cvs version) should work with the latest
cygwin dll , at least it did when I tried a few weeks ago (things change
pretty fast in the cygwin world)=20

Hi Reny,

You can simply run the program from a debugger.

Are you doing this on Windows ? or Unix ?

On Unix you have gdb, and its GUI front end
DDD. On Windows you simply use the Visual Studio
debugger.
