http://d.puremagic.com/issues/show_bug.cgi?id=2941 clugdbug yahoo.com.au changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |major I've found the cause: iasm.c, line 1650-1651 is: else if ((ptb.pptb0->usFlags & _fwait) && config.target_cpu >= TARGET_80386) { Turns out that at this point, config.target_cpu is uninitialized! It's 0! It doesn't get initialized until much later. (In obj_start() in glue.c). I suspect that there should be a call to out_config_init() (in msc.c) at a very much earlier point, possibly even in mars.c. As this could be causing all sorts of problems elsewhere, I'm raising the severity. --
