Program refuses to compile

[boriel]

Still more research:

The example above compiles fine and it even compiles fine with a = peek(b) bxor 255.

The example below does not compile under -O3.

dim a as ubyte
dim bPtr as uinteger

for bPtr = 32768 to 32768 + 25
a = peek(bPtr) bxor 255
poke bPtr, a
next bPtr

If you change bxor to 25 or any other number but 255 and 255 does translate to cpl in assembly then it does compile.
Now I do not have to share the source.
It is up to you now Boriel.

Can you please check the version 1.4.0-1877 and check if this is fixed, please (it should).
