gnustep-base tests

[Eric Heintzmann]

Hi,
I'm currently trying to build the official debian packages for the four 
gnustep core packages.

Gnustep-base1.24.9 builds fine but don't pass regression tests (make check):

 From the build logs:

base/NSInvocationOperation/basic.m:
Failed file:     basic.m aborted without running all tests!

base/NSNumberFormatter/basic10_4.m:
Failed test:         basic10_4.m:149 ... negativeFormat used for -ve number

 From test logs:

Also there is a segmentation fault when running the test (i think this 
related to the failed file)

What should i do to avoid these problems ?
Use another version of gcc (I used default debian gcc -- ie gcc 5)?
Use another compiler flags ? (i leave them untouched)

Thanks
Eric

PS
I build these packets in debian unstable under Vitualbox (amd64)
