#12477: [math] error: while reading precompiled header: No such file or directory
------------------------------+-------------------------
 Reporter:  jackie.huang@…    |      Owner:  johnmaddock
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  math
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:  pch               |
------------------------------+-------------------------
 Compilation of boost 1.61.1 with GCC 6.2.0 compiler sometimes fail (35%: 7
 failure out of 20 builds, with "-j64") with many erros like:

 -----------
 libs/math/build/../src/tr1/assoc_legendre.cpp:6:21: error: while reading
 precompiled header: No such file or directory
  #  include <pch.hpp>
                      ^
 libs/math/build/../src/tr1/cyl_bessel_j.cpp:6:21: error: while reading
 precompiled header: No such file or directory
  #  include <pch.hpp>
                      ^
 --------------

 It seems to be a race condition in parallel compiling.


 And I also observed many warnings like:

 BTW, my builds are based on yocto project.
