OK, this happened to me; no idea why. Searched the site for past experiences, applied all recommendations. Still happened on XP and Windows 7.

With no error report it has taken 4 days to find out that one line in 80,000 was causing the problem; following line


This turned out to be no different to many identical lines performing a basic UDT array insertion function call using the following UDT:


By creating a separate project with the problematic line UDTs, the error could not be reproduced.


I'm posting this experience as it might lead to a clue later on, but right now I have no idea what is wrong with the compiler or this code.

The suspected cause above is only a partial cause. Another cause, or the main cause of the problem is the function count; thus the complexity and size of the program.

The following snippet can be used to generate a large series of functions which when compiled, crash the compiler after the linking stage.

Once I go past roughly 2233 functions in my project; this problem occurs (I do not use sub-routines). Cutting out areas of the project fixed the issue, so I will resort splitting the project into two parts.

Something in the compiler has been exhausted, the test was run on two seperate machines and operating systems. Anyone who else who this happens to will need to restructure their work.

Maybe the compiler is running out of memory?

No, it doesn't appear to be caused by insufficient memory. The compilers memory usage immediately before the crash is 70 megabytes.

Well, at least the function stack limit seems reasonable. I managed to compile a function containing 7000 lines of code. Having to now squeeze more sardines into fewer cans, but all is going smoothly so far.
