What is the current bug behavior?

Compilation error with latest MSVC compiler when simply instantiating a Eigen::Vector4d.

The error is at

https://gitlab.com/libeigen/eigen/-/blob/master/Eigen/src/Eigenvalues/GeneralizedEigenSolver.h#L182

What is the expected correct behavior?

It should compile.

Relevant logs

[build] deps\Eigen\include\Eigen\src/Eigenvalues/GeneralizedEigenSolver.h(182,9): error C2760: syntax error: ')' was unexpected here; expected 'expression'

It is missing a semi-colon at the end of the line.MSVC does not like it at all.

• Have a plan to fix this issue. (busy today but can try provide the quick fix this evening)
