Eigen + VS2008 + DebugModus

Hi,

What I'm trying to do:
Making my code run in Visual Studio 2008 with the compiler options from the "release"-modus and the "debug"-modus.

The "release"-modus works fine.

The "debug"-modus produces the runtime error: UnalignedArrayAssert
(details:
http://eigen.tuxfamily.org/dox/Unaligne ... ssert.html
http://eigen.tuxfamily.org/dox/StructHa ... mbers.html )

But just adding EIGEN_MAKE_ALIGNED_OPERATOR_NEW to the public part of the class does not work.

Which kinda makes sense, because as far as I know, the debugger initialises classes in it's own weird way, maybe overlooking the macro.

Any hints on how to solve this problem? (or which feature to turn of in the debug-modus?)

There's no particular feature to turn off in the debug-mode as opposed to the release-mode. The debug-mode uses assertions and just working around them is not good enough, you need to understand them and fix them, otherwise you'll get uncontrolled crashes in release-mode.

If EIGEN_MAKE_ALIGNED_OPERATOR_NEW doesn't do the trick for you, it might be either because the cause of the problem is different (there are 3 other causes for this assertion) or because you're not using this macro at the right place.

If you need more help, paste here
- a complete backtrace of your crash
- the relevant sections of your code, including where you put EIGEN_MAKE_ALIGNED_OPERATOR_NEW.

Hi,

It works now and it worked fine the first time. (for the ONE class I've implemented it)
The crashes occurred from other classes, that also needed the macro.

But thanks for encouragement to take a second look at the crash site!
