SomeThing Strange! Maybe a Bug
June 14, 2007 12:40 AM
I use 2.8.0a
uint8 test2()
{
int i;
i += 3;
return 3;
}
uint8 test(uint8 port)
{
test2();
GlobalCharArray[1] = port;
PRINTS(HEX0(GlobalCharArray[1]));
return port;
}
main()
{
test(0x30);
}
it will print "0x01" not "0x30"
ps:
GlobalCharArray is a global uint8[]
I create it with
GlobalCharArray =(asIScriptArray*)engine->CreateScriptObject(engine->GetTypeIdByDecl(0, "uint8[]"));
GlobalCharArray->Resize(256);
r = engine->RegisterGlobalProperty("uint8[] GlobalCharArray", GlobalCharArray); assert( r >= 0 );
====================
1. If I replace "uint8 test2()" ===> "void test2()", the result is "0x30"
2. If I replace "uint8 test(uint8 port)" with "uint8 test(const uint8 port), the result is "0x30"
3. as 2, I replace "uint8 test(uint8 port)" with "uint8 test(uint8 ∈ port)" the result is "0x30"
4. If I just replace GlobalCharArray[1] with GlobalCharArray[5], then the result is "0x05"
5. If I reorder the codes like that:
GlobalCharArray[1] = port;
test2();
PRINTS(HEX0(GlobalCharArray[1]));
the result is "0x30"
It seems a Bug of AngelScript!

Interesting. It does indeed look like a bug in AS, and a strange one at that. I'll look into it.
There's been a lot of bug fixes for 2.8.1 WIP, would you mind giving the latest version in SVN a try (currently revision 152) to see if your problem remains in the new version?

For what it is worth, I tested this on the latest code in SVN and it worked as expected (printed out 0x30).
Here is the code I used:

I use the latest version from SVN.
The result are all "0x30" in my testing environment.
Thanks a lot

Excellent! Thanks for confirming that for me.
