Proposed patch for xrdb.c
Attached patch fixes the problem for me.

Your patch fixes these. Please raise the priority since this is a very ugly bug which should be fixed ASAP. Thanks, Helmut What is the upstream status of this? x11 team generally is reluctant to take patches which upstream has not even commented on. (In reply to comment #3) > What is the upstream status of this? Is bugs.freedesktop.org the right location to report this? (I hadn't contacted upstream, because I had assumed that the OpenSuSE folks would forward their identical issue.) Yes, report a bug at https://bugs.freedesktop.org/ and if possible, please also send a git formatted patch to xorg-devel@lists.x.org Reported upstream, see <http://bugs.freedesktop.org/show_bug.cgi?id=32701>. Created attachment 259295 [details, diff] xrdb-1.0.7-cpp.patch A modified patch has been applied upstream: <http://cgit.freedesktop.org/xorg/app/xrdb/commit/?id=117021570515fa985670f78d27376d636ed5490f> Upstream has rebased my patch though and it can't be used for xrdb-1.0.7 any more. Attached is the patch that I had originally sent and which cleanly applies to 1.0.7. This is fixed in xrdb-1.0.8. Therefore closing. |
I've the following in my .Xdefaults (unchanged since a long time): *VT100.Translations: #override \ <Key>BackSpace: string(0x7F)\n\ <Key>Delete: string("\033[3~") With xrdb-1.0.7 and gcc-4.5.1, the backslash for line continuation doesn't work any more. xrdb -q shows that each of the above lines will end up in an own resource: *VT100.Translations: #override <Key>BackSpace: string(0x7F)\n <Key>Delete: string("\033[3~") Whereas with gcc-4.4.5 everything is as it should be: *VT100.Translations: #override <Key>BackSpace: string(0x7F)\n <Key>Delete: string("\033[3~") The problem depends only on the gcc version selected at run time. It doesn't matter if xrdb is compiled with gcc 4.4 or 4.5. My guess is that it's caused by this change of C preprocessor behaviour: <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41748> So adding option -P or -traditional-cpp to the cpp call should fix the problem.
