A lot of functions in linalg/factorization.jl (and perhaps elsewhere in LinAlg) have methods like:

function eigfact!{T<:BlasReal}(A::StridedMatrix{T}) ... end
function eigfact!{T<:BlasComplex}(A::StridedMatrix{T}) ... end
eigfact!(A::StridedMatrix) = eigfact!(float(A))

This gives a stack overflow if float(A) does not return a BlasReal or BlasComplex, e.g. if eltype(A) is Float16 or BigFloat.

The text was updated successfully, but these errors were encountered:

Related: #11, #19. But even if we don't have these functions, we should give a MethodError or a BlasFloat result, not a stack overflow.
