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:
