This fix was never taken by LEGO and incorporated into the standard firmware. For this and many, many, many, many, many other reasons I highly recommend that you switch to using the enhanced firmware which is 100% compatible with the standard firmware but not broken like it is in several places. Th...

Can you show me the F12 code with until(1) and then show me the code with while(0) (which apparently works) for the current compiler at optimization level 3?

There's definitely something going wrong - possibly a floating point type opcode incompatibility of some kind. Can you try with different optimization levels to see if it is an optimizer bug or a code generator bug? My guess is it is in the optimizer. It's still frozen at optimize level 0. Also, ca...

Hello, I think this is the result of macro expansion. "until(x)" is defined as "while(!(x))". So at the end the statement is "while (!(1))". A real c compiler will make a "false" out of this but may be "nxc" is confused by that construction. Give &q...

Firmware is Lego official 1.31.
In the NXC config section, NXT2.0 compatible is checked, enhanced firmware is not.

Thanks for your reply.
The "frozen" mean the brick can't response for any operation, even power off.
The only thing i can do is take off battery.
