When that particular error happened erlydtl.git was at 3306858. It
doesn't happen with today's otp.git, but there's a new issue with
today's otp.git. Should I try to checkout otp.git from Jan 10th and
retry with that? erlydtl.git c18f2a0 also doesn't provoke the Jan 10th
issue when using otp.git.

$ cd otp
$ git describe
OTP_R15B03-1-1421-g9b01d95
$ git clean -fxdq
$ export ERL_TOP=$PWD
$ export PATH=$ERL_TOP/bin:$PATH
$ MAKEFLAGS=-j2 ./otp_build setup -a --prefix=$PWD/localinst
$ make install
$ export PATH=$PWD/localinst/bin:$PATH
$ dialyzer --build_plt --verbose --apps BIG_LIST_OF_APPS SOME_EBIN_DIRS
Compiling some key modules to native code...

It's stuck at that step:
$ ps -Ao fname,bsdtime,tmout,wchan|grep beam
beam.smp   0:30     - poll_schedule_timeout

I didn't enable --enable-native-libs because that breaks the build
right now, but I did so on Jan 10th.
