Memory limitations for Debug mode ?

When the Debug mode is ON during compilation of a large project (8000+ lines) in Dynamic C, we find that at some point the Debug mode gets disabled - the Breakpoints are removed and the project compiles as if the Debug mode was not enabled.

Are there any known limitations for memory size or lines-of-code ?

The PC shows that max DRAM memory utilization is less than 50% and there is enough free disk space.

We are using DC 7.25 on a board with 512KB Flash and 512KB SRAM and the code file size is around 380KB.

Any one else face similar problems ? Any known issues or bug fixes ?

Appreciate any inputs on this.
