MPLAB X + XC8 Compiler + PicKit3 + Interruption Debugging

Hello people,

I am wondering about the behaviour of the MPLAB debugger. I have the PicKit 3 provided by MPLAB. Thanks to this HW is possible to make code debuggings on real time using MPLAB X IDE. On the other hand I am compiling the code using XC8 compiler provided by MPLAB, too.

Then I have a bigo problem debugging interruptions. With small programs, everything is working fine. However with big programs with a lot of lines of code, the MPLAB debugger gets crazy and it gives me an error when I try to make the interruption debugging...

By default, the big program that I want to debug is waiting for one external interruption given by an FGPGA. But in the meantime, every 5 sec, a timer interruption is also enabled and the uC sends data to the FPGA. Then if I place the brakpoint inside of the interruption function the debugger crash and MPLAB IDE gives me an error related with the libaries of the compiler XC8.

Anyone knows what could happen? Maybe I need another hardware to debug big programs...

Thanks a lot.
