Can't debug/run on iOS 7.03,iPhone 5s

when you debug your ipa, run the application, and it will show the adobe alert

but it did not show on iOS 7.03,iPhone 5s,just crashed

my objective code:

#import "FlashRuntimeExtensions.h"

FREObject tryCall(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])

{

    FREObject retStr;

    FRENewObjectFromUTF8(1, (const uint8_t*)"", &retStr);

    return retStr;

}

void ANEContextInit(void* extData, const uint8_t* ctxType, FREContext ctx, uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet)

{

    *numFunctionsToTest = 1;

    FRENamedFunction* func = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * *numFunctionsToTest);

    func[0].name = (const uint8_t*) "tryCall";

    func[0].functionData = NULL;

    func[0].function = &tryCall;

    *functionsToSet = func;

}

void ANEInit(void** extDataToSet, FREContextInitializer * ctxInitializerToSet, FREContextFinalizer * ctxFinalizerToSet)

{

    *extDataToSet = NULL;

    *ctxInitializerToSet = &ANEContextInit;

}

i think it just a empty and,what should i do?how can i fix this? thank you
