          Issue ID: 14692
           Summary: SIGSEGV during SHA.put
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: rjmcguire at gmail.com

I get a SEGFAULT every time I try log in to my MySQL server using mysql-native
and vibe.d.
If I compile with GDC I do not have this problem, and I never used to have this
problem with previous versions of dmd, not sure which version etc yet.

Just logging this issue in the meantime so that I don't forget.

Backtrace:
Program received signal SIGSEGV, Segmentation fault.
