Bug#290782: Fwd: Re: Bug#290782: multi_array.hpp: rebasing via range causes a crash while reindex works
Enclosed is my confession to the upstream list. Should have CCed this here. You are welcome to close the bug (/me LARTed), unless you feel that the intro docs are vague enough for others to fall into the same trap and thus need exaction. -- Forwarded Message -- Subject: Re: Bug#290782: multi_array.hpp: rebasing via range causes a crash while reindex works Date: Wednesday 19 January 2005 08:18 From: Vassilii Khachaturov <[EMAIL PROTECTED]> To: boost@lists.boost.org > > arr a(boost::extents[ arr::extent_range(1, 1) ]); > > I'm not a multi.array user, but this is an invalid range. See > Table 4 [1] Invariants: > o Valid range [a.begin(),a.end()) is a valid range. Thanks. It looks like I have misunderstood the extent_range ctor semantics. Upon re-reading the multi_array reference page in its extent_range section, I see extent_range(index start, index finish) This constructor defines the half open interval [start,finish). The expression finish must be greater than start. (I assumed that finish is included in the interval, hence the snippet.)

hi all, boost debian package version 1.32.0-2 has been reported the following bug. i didn't find anything in the archive. is it a new entry? cheers domenico - Forwarded message from Vassilii Khachaturov <[EMAIL PROTECTED]> - Date: Sun, 16 Jan 2005 19:06:00 +0200 From: Vassilii Khachaturov <[EMAIL PROTECTED]> Subject: Bug#290782: multi_array.hpp: rebasing via range causes a crash while reindex works When a multi_array rebasing to 1 is attempted via extent_range, a segmentation fault happens on accessing the boundary element.
