Bug ID: 283698
Summary: New version of swab(3) breaks port graphics/dcraw
Product: Base System
Version: 15.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: misc
Assignee: b...@freebsd.org
Reporter: nwhiteh...@freebsd.org
The new version of swab(3) committed in
bac2eea13ae3e4dc8fd2aec261b2a18930138495 has slightly different semantics than
the old version. In particular, if the input and output buffers are identical,
the old version will work, but the new one -- which does not use a temporary
buffer like the old one did -- will not.
Strictly speaking, this is fine since the input and output pointers are marked
'restrict' so cannot be identical, but at least one program in the wild
(graphics/dcraw and all the versions of it in other photography programs) uses
identical buffers anyway and expects it to work.
Closing this "won't fix" is legitimate -- I will alert the dcraw developers as
well, since the bug is clearly on their end -- but I wanted to also write
something here since there appear to be compatibility implications both
relative to Linux and older versions of FreeBSD.
