I've just started trying to install version 1.60 of boost using the gcc 5.3.0 compiler. With a vanilla download and no chnages it all seems to compile correctly, but I have a problem with 2 library regressions tests not terminating. They have both run for over 18 hours before I had to kill them. I was using the options and configuration "out of the box" so optimization was -O3.

I'm unable to reproduce on Ubuntu x64, all the Math lib tests pass fine for me with gcc-5.3.0 in both C++03 and C++11 modes.

So you'll need to debug and supply a patch if you're able,

Thanks, John.

I'm trying to find out what exactly is causing the issue here. Would it be possible for you to show me the 'gcc -###' output so that I can compare to my version of gcc. Since the failure occurs only with optimization turned on i'm now leaning towards a compiler issue since I compiled gcc from source for this test. I'm hoping it's something obvious when I look closer. So far this has failed on a RHEL6.5 system running a locally compiler gcc 5.3.0 as well as a RHEL 7.2 based system compiled with the same gcc 5.3.0. Many thanks for your help, S
