I have the same issue here. I do a git clean -dxf, then a

LD=/usr/bin/ld.gold CFLAGS="$CFLAGS -g -ggdb -Wall -Wextra -Wno-unused-parameter -Wno-missing-field-initializers" ./configure.developer --with-cluster-support --abi-check-disable --with-profiling-data --prefix=/root/git/inst --enable-spotlight && nice -n 19 make -j -k

When that finishes, I do a

SELFTEST_TESTENV=ad_dc_ntvfs make testenv SCREEN=1

and that re-builds the world. So on my CPU it takes ages to get the
testenv up and running. And if I Control-C the "make testenv" it
always starts from scratch. So I have to really sit through the whole
build every time I want a testenv.

I did not do a "git bisect" yet. If that is required for analysis, I
can do that. But it will be a lot of waiting.

With best regards,
