[Bug 1365748] Re: gcc-4.8/6.8 on Ubuntu 14.04 has a bug in link-time optimization

 

To clarify:

The specific "gnulib" tests fail due to "pthread"-related issue of the link-time optimization used with gcc-4.6 and 4.8.
same tests on same machine do not fail with gcc-4.4  or clang-3.3.

The workaround provided by Paul Eggert is to use "-pthread" instead of
"-lpthread" as command-line parameter.
