Description Alex Parrill 2016-04-04 23:23:52 UTC 
Probably related to https://issues.dlang.org/show_bug.cgi?id=15855, though it apparently applies to more than just the for keyword.

Example file contents (one file per line):

    o[{scope(x
    o[{template
    d(={for
    typeof){for
    p[{alias
    p(={alias

Similar to the linked issue, DMD spits out some error messages and then terminates with a segfault. DMD v2.070.2

These two don't segfault anymore with git master (6199fd3).
Comment 2 Nicholas Wilson 2018-11-24 11:18:49 UTC 
none of these segfault anymore
Comment 3 ag0aep6g 2018-11-24 14:28:12 UTC 
Reopening. I still get segfaults. Tested with git master (DMD64 D Compiler v2.083.0-326-g1e902fc61). Remember to test one line at a time, not all at once.
