Testcase code: ``` void foo(out byte[0] v) { } ``` Testcase cmdline: `dmd -c dsymbolsem_assert.d` This asserts in dsymbolsem.d: https://github.com/dlang/dmd/blob/67ccf216a20e5b45b0fd4136a750b07ded4c8461/src/dmd/dsymbolsem.d#L1427 If anything, this needs better diagnostics (easy to implement a printout of the function and param for which the error happens).

All ICEs are critical! A simple PR that triggers an error instead of the ICE: https://github.com/dlang/dmd/pull/8127
