Hi Nicolas,
Ok here are the details about the crash. What I am trying to do is to read an
1.5 mb XML file and put parts of its contents into a database in many queries
(thousands of them). The program crashes with the following messages in VS
output:

HEAP[neko.exe]: Invalid Address specified to RtlValidateHeap( 02540000,
03027088 )
Windows has triggered a breakpoint in neko.exe.
This may be due to a corruption of the heap, which indicates a bug in neko.exe
or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while neko.exe has focus.
The output window may have more diagnostic information.

Any pointers where to look further? These VM internals seem cryptic for me...
The line 479 in neko.dll is
ret = val_callN(f,val_array_ptr(args),val_array_size(args));
where f is shown as VAT_JITFUN. Probably something about JIT.. How to disable
it at least? And best to fix :)

Hi Nicolas,
Thanks a lot for the tip, works now! Debugging some mysterious crash in neko,
will post some findings soon (probably).

You can comment __ftol2, remove msvcrt60.lib, and remove MSVCRT from the
Ignored Libraries, and it should work.
The reason for these is explained here :
