My application https://bitbucket.org/eschnett/block-matrix encounters a segfault with HPX a3382fb and some of its predecessors.

I start with

./bin/block_matrix --hpx:debug-hpx-log=block_matrix.log --nsize=200 --nblocks=8

This is my backtrace:

Program received signal SIGSEGV, Segmentation fault.

I'm pretty sure this is yet another case related to #588. Does it happen on the fixing_588 branch as well?
