the error is probably related to the fact that formats are no longer dealt with in the same way
Actually, this particular warning is a glitch in itself, it seems a (quite harmless) case of forgetting to clear the condition state. Nevertheless, there are numerous other problems with mpost 1.500 that I have already fixed, so I may well release 1.501 tomorrow just to get rid of the most obnoxious bugs in 1.500. A side note: besides the alpha state of the code, running mpost 1.500 to dump a mem file is pointless: all it does is generate a log file, no actual mem file is created. This is by design: $ metafun myfile if 'metafun' is a link to mpost version, simply loads 'metafun.mp' as a preloaded source file instead of looking for an actual metafun.mem. Best wishes, Taco
