Hi Phil, The problem was caused by the assumption that sizeof(int) == sizeof(XID), however Xlib uses unsigned long for XIDs, even if XIDs are defined to be 32-bit on wire. According to the xorg mailing list ists safe to store those values in 4-byte variables, the only case which needs attention are arrays.
In this case the problem was I passed a Glyph* to XRenderCompositeText, which however expected a unsigned int*. Both are 4bytes wide on ia32, but Glyph is 8 bytes on amd64. XRenderFreeGlyphs was also affected. - Clemens PS: I can't access information for 7029934 - which seems to be rather common for many bug-numbers I see floating arround on the mailing lists. Any idea why? 2011/3/22 Clemens Eisserer <[email protected]>: > Hi Phil, > > I'll have a look at this one soon. > I also hope to fix the bug causing intellij's editor to be completly > unuseable before jdk7's freeze phase - however I guess I'll need a > little help for that. > > Just remembered that I promies results some time ago, sorry, I'll send it > soon. > Its just, university is giving me a really hard time.
