pure virtual function call

hi there,

i'm facing the problem that MATLAB crashes occasionally with the error message "pure virtual function call".

the stack trace from the dump-file looks as follows:

Stack Trace (captured):

...

so, as far as i can read this, theres some dll trying to call an abstract(virtual) function. any ideas how this can happen?????? or how to debug such a problem?

my assumption is that it is caused by some memory problems, since the application has runtimes of several hours and runs on a 32bit winXP machine, but i have no idea how to get around this.

sincerely, steffen

Could you paste the line in your MATLAB code at which this failure occurs - you can do this by using the debugger to step through your code and figure out which line the crash occurs at. Even better if you have a code snippet that can reproduce the issue.
