I would be interested in seeing your backtrace, even without line numbers to see if you are crashing with some of the same calls.
If you can capture a few backtraces of the crashes you see, then that at least might point to something in common.
I can't do backtraces right now. :-(
One, I have been focused on getting the build process running for the new environments. I did not need nor want that overhead during this phase.
Second, now that I can build without incident in these new environments, something is messed up with my build scripts. For a while I was building separate debug packages and they worked just fine. A couple of weeks ago I noticed none of them worked. That is, several times I could not obtain backtraces (TDM has a habit of crashing on my system). I likely can temporarily build the packages with debugging built in, but that makes for huge packages.
