Working on it now, it's definitely a weird one. You have to allocate 3 different memory segments, of certain sizes, and then one memory segment has to be no-pointers, where the other isn't. Then you have to trick the array appending code into copying the no-pointers flag to a pointers-containing block, and then get the corruption to occur. I hope I can deterministically make it happen.
Ellery's code, which uses appending all over the place, would not deterministically reproduce it (probably 1 out of 4 runs), and that was a huge piece of code. -Steve ----- Original Message ---- > From: Walter Bright <[email protected]> > To: Discuss the phobos library for D <[email protected]> > Sent: Tue, April 6, 2010 7:30:53 PM > Subject: Re: [phobos] Looks like more problems with the array append patches > > Thank you.
