Oh, interesting ;-) Thanks for this explanation. Another data point is: calloc is not correct for pointer fields, you have to manually assign NULL to them afterwards still, because NULL doesn’t have to be represented by all-zero bytes (e.g. TenDRA supports having 0x55555555 as NULL pointer as an option). bye, //mirabilos -- 15:41⎜<Lo-lan-do:#fusionforge> Somebody write a testsuite for helloworld :-)
