I used mcc18 v2.43 compiled my project, the result is correct, but when i upgrade v2.43 to v2.44, the result is mistake. when I trace into task call, i found all parameter equal to 0 which be transmited to function call. i think that is compiler bug, but i can’t fix it. what can i do to fix this bug? someone can help me?

I only have V2.4.0 which is working fine.  Looking through the change history between 2.4.0 and 2.4.4 there have been several compiler bug fixes, but nothing that looks like it could cause this problem. Make sure you are also using the latest versions of the linker and IDE.  Also make sure you do a complete rebuild and that the paths are setup correctly as specified on the FreeRTOS WEB site port page for the MPLAB port.

The mistake is disappear when i replace my computer system.In this beore, I reinstall my windows 2000 pro  with SP4 twice which it appear same behavies, when i reinstall MPLAB 7.20 + mcc18 v2.43 to other computer, the mistake is disappear, all task is runnng fine! But other program except mcc18 compiler is running fine! I think may be mc18 have compatibility problem or other reason. thank’s everybody for me! surixwang.
