Compiled the latest source (no errors) (using codeblocks) then when I ran it, the line above was shown (nothing else before that, except a console window).
If this is system related then:
2.2 GHz Intel Core 2 Duo 2.00GB RAM Windows 7 Home Premium 64-bit
hmm crash on start? sounds like the issue of being 64-bit, this was just fixed a few days ago and it isn't in Simon's branch. you can use jacksonmj's or dikzak's branch, or just add #include "marshal.h" to main.c, https://github.com/jacksonmj/The-Powder-Toy/commit/07b07f856e2ce0e069fa9015d2d9ed8b2ebd5a95 EDIT: simon just updated his branch with the changes, you can update to that now if you want.
