This is most likely an optimization issue; also if you are comparing 
1.2.x to pre-1.2.x you will see large differences due to the use of 
inlining in the older versions. Another possibility is that one of these 
compiles had "-g" in CFLAGS for some reason, which produced debugging 
information in the object files.

It could be, one possibility if you can manage it is to set up a serial 
console for the kernel, so if there are any messages that you aren't 
seeing because of the crash you could still capture them. Otherwise 
you're going to have to add some type of "telemetry" to your profile so 
you can at least find out during what part of the build it's failing.
