Subject: Disable floating point exceptions in some scalapack tests.
X-Git-Tag: v9.1.0-rc1~110^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F8027%2Fhead;p=dealii.git

Disable floating point exceptions in some scalapack tests.

Since these tests only verify that we can save and load scalapack matrices
correctly the floating point exceptions are not relevant.
