Trying to call a fortran function. The fortran library is qrupdate. The fortran files were compiled with flags
-fimplicit-none -O3 -funroll-loops -fPIC
using gfortran.
My julia command looks like
ccall(("sqrinr_","qrupdate-1.1.2/libqrupdate"), Int32, (Int64, Int64, Array{Float64, 2}, Int64, Array{Float64, 2}, Int64, Int64, Array{Float64, 1}, Array{Float64, 1}), n, q, Q, n+1, R, n+1, n, xp, w)
and I get a segfault
signal (11): Segmentation fault
while loading no file, in expression starting on line 0

I have no idea how to approach the problem, can someone point me in right direction?
