Hey Benoit, thx for the reply.
- no optimizations (-O0), default debugging info (-g).
After changing code to read k, I get the same result.
Torben.
UInt16 g_Stuff = 10;
UInt32 PilotMain (UInt16 cmd, void *cmdPBP, UInt16 launchFlags)
{
static UInt16 k = 0;
UInt16 j = 0;
k = k + 1;
j = k + 2;
return errNone;
}
