Ubuntu 16.04 -> 18.04 => one unittest failure

[Jean-Baptiste Faure]

Hi,

Since I migrated my PC from Ubuntu 16.04 to Ubuntu 18.04 (both 64 bits), 
I get a unit test failure each time I build LO 6.1.1 and the master.

The end of the error message is the following:

> testN757910::Import_Export_Import finished in: 83ms

This test passed without problem under Ubuntu 16.04. My autogen.input 
file is the same under Ubuntu 18.04 as it was under Ubuntu 16.04. 
Compiler version is the same (gcc 7.3.0).

I tried make CppunitTest_sw_ww8export CPPUNITTRACE="gdb --args" and did 
see anything relevant: the code run normally, it only don't return the 
expected result.

The other two suggestions do not seem relevant  to me in this case.

What could I do to fix this issue ?

Best regards.
