Hello
I just tried to compile diStorm (http://ragestorm.net/distorm/) with TCC.
Everything works well, except one bug I found.
It seems you can't cast a pointer from a specified offset:
char* s = "\x34\x34\x12";
short word = *(short*)&s[1]; // <--buggy
printf("%x", word);
will print 34 instead of 1234 (on LE machine, of course).
I also took a look at the generated code and it seems it simply ignores
the cast to short and reads a byte.
The bug can be triggered when specifying offset to access the buffer,
without the [XXX] it won't generate erroneously code.
Can anyone confirm?
Thanks,
Gil
