Tim, Darrell, All: I rebuilt TDE from 4/1 sources with full debug in attempt to further look into the kwrite crash that Darrell and I have experienced with TDE built on gcc 4.7. With this build, if it is a source/bad patch/tde issue, then with my 3/29 build giving no crash and my 4/1 build crashing, that would point to some problem in between those two dates. However, I am coming around to the thought that -- this isn't a TDE problem and is more likely a problem introduced by the gcc 4.7 interpretation of the TDE code. I will still have to build the 3/29 sources with gcc 4.7 to confirm that to be the case. I have 3/29 binaries that work fine (which I'm fairly sure were built on gcc 4.7, but I can't remember). If I rebuild with gcc47 on the 3/29 sources and get the same failure -- that, in my mind, conclusively points to the problem being gcc47. If that is the case -- how in the heck do you debug something like that? I don't even know where to begin. (well, I do, but that's by asking). So with full debug packages built, on the 4/1 sources, I get the following backtrace. If this doesn't point to anything specific, then all we can do is wait on the 3/29 build to finish. Let me know if you see anything in this backtrace: 0x00007f1723b65947 in KateLineRange (this=0x7ffffcad3100) at /build/src/tdelibs/kate/part/katelinerange.h:25 25 /build/src/tdelibs/kate/part/katelinerange.h: No such file or directory.
