Bug#949037: plplot: testsuite regressions on !amd64 architectures

[Gianfranco Costamagna]

Source: plplot
Version: 5.15.0+dfsg-10
Severity: serious

Hello, I noticed that the -10 upload regressed autopkgtests everywhere except amd64.
I'm thinking about a serious regression because of the new flags,

the same happened in Ubuntu if you want more logs
http://autopkgtest.ubuntu.com/packages/plplot/focal/arm64
(look for version 10ubuntu1)

thanks for having a look
