Hi, I encountered a strange error that I wanted to report in case it affects current development, in which an scf calculation fails in the nightly development (#19173) but succeeds in 5.1.2. Both are compiled on a multi-core linux desktop.
When noncollinear calculation is specified, and a potential from the sg15 database is used ( http://fpmd.ucdavis.edu/qso/potentials/sg15_oncv/ ), in the newest development version only I get an error right after "starting wfc are random" is printed: Error in routine cdiaghg (7): eigenvectors failed to converge The calculation proceeds normally with a separate NC pseudopotential from D. Ceresoli's library, and proceeds normally in 5.1.2. I've created a tarball with stripped-down inputs and outputs that exhibit the successful and unsuccessful runs, in case that helps: https://dl.dropboxusercontent.com/u/2715514/qe_conv_test.tar.gz Best, Peter
