Hi,

cad/stepcode is reported as runaway in -CURRENT. It seems to take
forever to compile chemas/sdai_wip210e3/SdaiAll.cc. (it uses clang
5.0.0)

What strikes me is that it compiles in my machine in about 10 minutes
in 11.1 with clang4.0

I attached a debugger to the c++ process that was eating 100% of the
CPU time and stopped it from time to time to get a backtrace. It is
always in this function:

DAGCombiner::MergeConsecutiveStores

I finally stopped the compilation since it seemed it wasn't going to finish.

Has anyone seen something like this?

Thanks in advance.
