Where test.d contains: void fn(uint x){uint a = 0 << x;} This works fine: > dmd test.d -main This does not: > dmd test.d -main -O -inline Segmentation fault: 11 This bug seems to only occur when both the -O and -inline compilation flags are present.

Actually this occurs with the -O flag, independent of -inline
