Test failure: FileUtilsTest.testSetFileLength

[vincele]

The following test failure happens on GNU Guix, both with version 3.0.7 & 3.0.8. This ran in a qemu/libvirt VM:

vince@guix /tmp/guix-build-lucene++-3.0.8.drv-2/build$ ./src/test/lucene++-tester --test_dir=../source/src/test/testfiles --gtest_filter=FileUtilsTest.testSetFileLength
Note: Google Test filter = FileUtilsTest.testSetFileLength

I repeated that single test a few times, and they all failed.

All the other tests pass OK.
