Subject: handle empty test output
X-Git-Tag: v8.4.0-rc2~39^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F2133%2Fhead;p=dealii.git

handle empty test output

If the make command to compile a test returns empty output (don't ask me
why that happened on my machine), quote it in the regex to avoid an
error like:
"string sub-command REGEX, mode MATCH needs at least 5 arguments"
