So your system setup is exactly the same (except me running on CPU: Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz) and I can conform that the following code
A = sparse([rand() + rand() * im for i in 1:100, j in 1:100]) B = [rand() + rand() * im for i in 1:100] A\B leads to the following error: julia: symbol lookup error: /usr/bin/../lib/julia/libcholmod.so: undefined symbol: zpotrf_ pacman -Qo /usr/lib/libcholmod.so /usr/lib/libcholmod.so is owned by suitesparse 4.4.1-1 *but* the PKGBUILD at https://projects.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/julia tells me that the Julia package was build with USE_SYSTEM_SUITESPARSE=0 I am currently building the Julia from the PKGBUILD in order to confirm that these build-options lead to the problem.
