--- Comment #54 from Tomas Kalibera <tomas.kalibera at gmail dot com> --- (In reply to Jakub Jelinek from comment #53) > Backported to 7.x, please test it. Thanks! I tested the default behavior with DPOSV and reference LAPACK, where it worked fine. Also with all of CRAN+BIOC R packages - there is one newly failing package with 275369 compared to gfortran 7 from Ubuntu 7.4.0-8ubuntu1 with -fno-optimize-sibling-calls, but I don't think it is related to the change.
