Would a bjam.log from a failing RHEL machine help?
There is everything from:
../libs/multiprecision/test/test_rat_float_interconv.cpp:195: error: '>>'
should be '> >' within a nested template argument list
hared_ptr.h:146: error: cannot use typeid with -fno-rtti
It takes 12min for my build to fail, I could up the build once an hour if
that might help. I could even auto upload the bjam.log to the regression

If we want to continue down this route, I would rather fix it than revert
it. It is the develop branch, things break, they get fixed.

I had brought up the issue with the headers target in the past on the
For it to work for me I use:
This was a breaking change in 1.56 for our codebase as before we simply
included the /boost//headers target. If this is the intended behavior of
use and implicit-dependancy I think it is possible to make the headers
target an alias that has a usage-requirement of the use and
implicit-dependancy of the real headers target. This would make the
headers target behave like it did before 1.56. There seemed to be little
interest when I brought it up before, I think I was the only one affected
at the time.
