Description FeepingCreature 2018-03-23 18:20:01 UTC 
Repro:

echo "import std.datetime;" > a.d
echo "import c;" > b.d
echo "import std.algorithm; const var = sort(string[].init);" > c.d
dmd -deps a.d b.d

Outcome:

core.exception.AssertError@dmd/glue.d(777): Assertion failure (segfault in release)
Comment 1 RazvanN 2018-03-26 11:47:58 UTC 
It looks like the order in which the files are provided matters:

dmd -deps b.d a.d works as expected

also working:

dmd -deps a.d b.d c.d
dmd -deps c.d b.d
dmd -deps b.d c.d
