 Does removing the third and fourth parameter from line 432 in ngen.c stop triggering the assert?

 The assert still happens after removing the third and fourth parameters (0,0)

 Ok, thanks. If the mask (third parameter) is set to 0xffff, then does that clear it up?

 Doesn't seem to help, unfortunately.

 Finally got around to making a debug build, should be fixed now in current GIT code.
