I am chasing a problem with an XE7 app which throws an "Invalid pointer operation" error. The difficulty is, this occurs only when the app is built on our build machine, and not in the development environment. We use EurekaLog, but the error does not result in an ELF file being produced.

I am chasing a problem with an XE7 app which throws an "Invalid pointer operation" error. The difficulty is, this occurs only when the app is built on our build machine, and not in the development environment. We use EurekaLog, but the error does not result in an ELF file being produced. 

I am nearly at my wit's end trying to imagine a method for locating the cause. Since we cannot reproduce in the development environment, we cannot find it in debug. 

I have checked the build options in use on our build machine against those in our development environment, and found no difference.

Suggestions?
