Subject: Tests: base/utilities_13.cc - workaround for clang
X-Git-Tag: v9.1.0-rc1~647^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b04e02d077cf9f6fbf744319a464c1e447caa81f;p=dealii.git

Tests: base/utilities_13.cc - workaround for clang

Clang issues a spurious arithmetic exception if this code snippet is
called with a reference long double pointing into the vector. Work
around this issue by explicitly writing out the long double twice.
