[vtkusers] 5.0 vtk crash with /MT build on windows

[David Cole]

Usually this means that the "new" was performed with either (1) the
statically linked in MSVC runtime libraries or (2) the dll version of MSVCRT
and the "delete" is being performed by the other one. This sort of mismatch
will almost always eventually lead to a heap corruption.

All of your components that do cross-component new/delete operations have to
be linked to the same flavor (static or dll) or the MSVC runtime libraries.

Are you sure that *everything* is compiled with /MT??

I would try starting again with a clean binary directory to ensure that /MT
is actually used to compile *everything*. Then, also make sure there are no
other versions of VTK dll's in your PATH environment variable.

If it still happens after that, we can continue discussing other ways to
figure out why this might be happening for you..... It should work.


HTH,
David
