The version v0.31.1 of Xcpc has been released !
What’s new ?
This release is a bugfix version …
This new version includes a quick fix on my original Xdnd implementation.
A nice user of xcpc on a netbsd distro on a Sun Sparc has reported a fairly old bug that has been present since 2007. After analysis, I found a misuse of XChangeProperty which produces a SIGBUS error on 64-bits big-endian systems. This Xlib function requires 32-bits properties to be encoded with long integers, even on 64-bits platforms …
Damn it ! It’s just one line of code … Thanks to Connor McLaughlan for the bug report.
