---------------------------------+------------------------------------------
A fresh build from scratch of the "master" branch from the GHC repository
runs into the following problem if the build flavour is set to "quickest"
in mk/build.mk file:
{{{
BuildFlavour = quickest
}}}
The compiler successfully passes stage 0 and the last lines of stage 1
(run with verbosity level V=1) look as follows:
{{{
