CppunitTest_vcl_graphic_test fails on 7.1 and master branches

[Jean-Baptiste Faure]

Hi,

CppunitTest_vcl_graphic_test fails on 7.1 and master branches with homemade builds under 
Ubuntu 18.04 x86-64.
LO 7.1 is build with gcc 7.5 (default version for Ubuntu 18.04) and master is build with 
gcc-11. Same problem if LO 7.1 is build with gcc-10.

Terminal output:

Additional Info:
I don't have the skills to debug this. :-(
I observed this failure since my first builds of branch 7.1.
