Hi,
I am using RVDS 4.0 trial version. When I compile my app using OTime O3 compiler flag, the application crashes. But if I specify O2 then it is working properly.

My compiler flags are :

-DRVCT -DDYNAMIC_APP -DBREW --cpu=ARM926EJ-S --apcs=/ropi/interwork/norwpi -c -Otime -O2 --littleend --split_sections -zo


My linker flags are:

--split --reloc --entry AEEMod_Load --first AEEMod_Load --callgraph

please do let me know if i need to specify anything else in the compiler/linker flag options

    In addition, it's also possible that you've done something in your code which isn't guaranteed to do what you think. The C specification is quite vague about a number of things, and turning up the optimization level can expose bugs in which the code makes assumptions about how data will be stored or handled. Finding these bugs can be very difficult.
