Crash when importing sub-submodules #2018

Open ximion opened 7 years ago

ximion commented 7 years ago

As soon as one imports a module with a nesting level of 2 or higher (import aaa.bbb) with a package.d file at the root, LDC crashes.

Meh, Github doesn't let me attach files... EDIT: Attached the previously linked file to the bugreport.

JohanEngelen commented 7 years ago

@ximion Especially if the files are small, it is easier for us if you paste them here.

This is a front-end issue, DMD 2.073.1 segfaults too. @ximion: Please file an upstream issue.
