Hi all,

When linking to this library from D, I have declared it as:
extern __gshared const(char)* seq_nt16_str;
***But this segfaults when I treat it like an array (e.g. by
accessing members by index).***
I believe this should be extern extern(C)? I'm surprised that
this segfaults rather than having a link error.
A bare `extern` means "this symbol is defined somewhere else".
`extern(C)` means "this symbol should have C linkage".
I am so sorry -- I should have been more clear that this is in
the context of a large header-to-D translation .d file, so the
whole thing is wrapped in extern(C) via an extern(C): at the
top of the file.
In case you weren't aware of it, take a look at atilaneves DPP on
GitHub or code.dlang.org. auto translates C headers at build
time and mostly it just works. If it doesn't, file an issue and
in time it will be fixed.
