same problem with openbsd 3.9 on sparc64, the workaround worked for me so far. running xorg 7.2.0 and this is still a problem. Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future. All protocol XID types should derive from CARD32 in the server; where that isn't happening, it needs to be fixed. fixed in renderproto-0.9.3 and server master. Leaving open for merge of dependency to server-1.4-branch. |

Hello, on PPC64 (most?) gtk applications crash on startup with the following error (for example the news reader pan): The program 'pan' received an X Window System error. This probably reflects a bug in the program. The error was 'RenderBadGlyphSet (invalid GlyphSet parameter)'. (Details: serial 2041 error_code 182 request_code 154 minor_code 23) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) this would be a workaround: ############################################################################## diff -Nur xorg-server-1.1.0.orig/render/render.c xorg-server-1.1.0/render/render.c --- xorg-server-1.1.0.orig/render/render.c 2005-08-29 04:47:39.000000000 +0900 +++ xorg-server-1.1.0/render/render.c 2006-04-29 18:11:54.596137060 +0900 @@ -1340,7 +1340,7 @@ { if (buffer + sizeof (GlyphSet) < end) { - memcpy(&gs, buffer, sizeof(GlyphSet)); + gs = *(CARD32 *) buffer; glyphSet = (GlyphSetPtr) SecurityLookupIDByType (client, gs, GlyphSetType, ############################################################################## [quote from http://bugs.gentoo.org/show_bug.cgi?id=112355 comment #14] Michel Dänzer pointed out that 'typedef unsigned long GlyphSet' isn't the same size on 32/64 bit architectures, so either the Render protocol or server code isn't 32/64 clean. [\quote] This only happens with gtk applications. I've never seen this with an qt application or something else.
