[eigen] the "Complex" test crashes randomly

[Thomas Capricelli <orzel@xxxxxxxxxxxxxxx>]

Hello,

Using the latest repository, In unsupported, the "Complex" is often failing 
here, though not always. 

-------------
 15/ 16 Testing FFTW                             Passed
 16/ 16 Testing Complex                       ***Failed

94% tests passed, 1 tests failed out of 16

The following tests FAILED:
         16 - Complex (Failed)
Errors while running CTest
make: *** [test] Error 8
----------------


Actually, it segfaults : here are two successive runs, where only one 
crashes..:

I have no idea what's wrong..
