[Tinycc-devel] tcc array bounds error?

[Somchai Smythe]

Hello,

    From the snapshot of tcc mob I downloaded today, I see this when I compile:

clang -o x86_64-gen.o -c x86_64-gen.c -DTCC_TARGET_X86_64     -O3 -m64
-march=x86-64 -mtune=generic -pipe -fno-strict-aliasing
-Wno-pointer-sign -Wno-sign-compare -Wno-unused-result -m64

Should I be worried, or is this expected?  The self-tests passed anyway.

Thanks!
