Locale setting and unittests

On a standard Ubuntu 13.10-setup the CombinedUnitests fails with errors referring to boost lexical cast:

$ ./unittests/combined/combined_unittest

*** 7 failures detected in test suite "CombinedTest"

while setting the LC_NUMERIC to en_US.UTF-8 works, i.e. running the program as
LC_NUMERIC="en_US.UTF-8" ./unittests/combined/combined_unittest

Also running the modelxml_unittest seperately does not exhibit the same errors.

Isn't this the same issue we had in the FRView VTK-parser? The fix there was setlocale to "C" afairc.

Kinda, but the weird thing is that it doesn't happen when we run the modelxml-unittests isolated. So the locale must be changed before it reaches the modelxml-unittests somehow.

So to repeat:

• modelxml_unittest runs without errors
• combined_unittest gives 7 errors from the modelxml-unittests
• LC_NUMERIC="en_US.UTF-8" combined_unittest runs without errors
