The dependencies in debian/rules are indeed correct, but now I have
figured out what the problem is: the upstream build system causes the
libraries to be relinked when make is run again, e.g. when debian/rules
runs "make install" to install them into debian/tmp. I have reported
this upstream at
Since the event of R³ support in dpkg/debhelper and the reorganization
of the build-arch/build-indep targets in ncurses 6.1+20180210-4, it is
possible that the binary-indep and build-arch targets are run in
parallel. In particular, the install-indep and build-test targets can
run in parallel, and then you have a race condition due to the relinking
of the libraries on which the test programs depend.
Until a proper fix is available, a possible workaround is to build the
test programs in the build-indep target (untested):
