https://bugs.winehq.org/show_bug.cgi?id=38266 --- Comment #2 from Bruno Jesus <00cpxxx(a)gmail.com> --- Not sure how to test this. I compiled the testcase in mingw and the results in vanilla or patched wine (from bug 37149) is the same: 6741961161019537394602307493150652354869067776.0000000000 If I compile the testcase on Visual Studio 6 the result is (which is the same as XP with this binary): 6741961161019537400000000000000000000000000000.0000000000 Native binary compiled with gcc (same result as mingw): 6741961161019537394602307493150652354869067776.0000000000 So I guess the the compiler is resolving the function on its own and not linking. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
