all applications and demos have a error wihile loading dll

Assertion failed!
program:...
File:..\..\magick\string.c
Line:773
Expression:string!=(char*)NULL

......

But everything works fine after I ignore this error.

To make ImageMagick more secure than it already is we've added a number of additional sanity checks. It looks like somewhere in the code, something is trying to destroy a NULL string. However, we cannot reproduce the problem. We ran all the demos and they ran fine without complaint. To investigate further we will need a method to reproduce the problem or a stack trace.
