We must find out where exactly the segfault happens. You can either look up how to set breakpoints and step through the code, or use good 'ol printf debugging :-)

This is the backtrace with Msys2:

The following solution popped up in my head: compile the object twice, one time with -DPD_FLOATSIZE=32 and another time with -DPD_FLOATSIZE=64, with different setup functions based on -DPD_FLOATSIZE, then link it with a third file which exports the "real" setup function (which calls the other two private setup functions). >>>> >>>> Is there an easier way? >>>> >>>> If not, then a new extension could be handy, so people can throw both versions into the same folder. >>>> >>>> Christof >>>> >>>>> Gesendet: Dienstag, 10.
