Hi Eric, I ran the whole stackless tests again. First I used my tiny optimisation, but the fifth test crashes after eating all memory. Then I switched back to your latest version, with the same result. Then I disabled the patch completely, and things worked, again. We must be missing something, no idea what. As an addition, the fifteenth test always crashes with too many heap sections (on windows). ciao - chris -- Christian Tismer :^) <mailto:tismer@stackless.com> tismerysoft GmbH : Have a break!
