Description Jerry Quinn 2009-02-01 12:34:37 UTC 
auto s = "string"; // s is type char[6]

Unless I'm misreading the spec, the type of s should be invariant(char)[6].
Comment 1 Jarrett Billingsley 2009-02-01 12:43:00 UTC 
Uh, what compiler version are you using?  If you're using a D1 compiler, then it should be char[6].

Sorry, I'm referring to D2.  Also, this is an issue with the spec web page, so the language version is in the URL and unambiguous :-)
Comment 3 Jarrett Billingsley 2009-02-01 13:42:26 UTC 
Both the D1 and D2 specs are on Digital Mars' site, so no, it's not unambiguous.

The URL includes 2.0 in the path.  But I'll try to remember to set the version next time, sorry.
Comment 5 Koroskin Denis 2009-02-01 16:53:53 UTC 
shall we close the issue?
Comment 6 Brad Roberts 2009-02-01 16:59:37 UTC 
Why?  string literals should be invariant in D2, so if that's not what's happening, then there's really a bug here.  Is this report strictly a documentation bug or was there also code associated to demonstrate the problem?

I'm assuming it's strictly a doc issue at the moment.
Comment 7 Brad Roberts 2009-02-01 17:03:13 UTC 
Fixed in svn revision 906, pending next release.
Comment 8 Leandro Lucarella 2009-12-07 15:02:02 UTC 
Fixed 10 months ago (probably in DMD 2.025). It's unlisted in the changelog.
