If there is any way you can retrieve human-readable backtrace with
source file line numbers etc which we can use to identify the particular
problem code it would be useful. Until then we will have a hard time
figuring out exactly what optimizations and code re-organizing has been
done by the compiler.

Also, please check as many as possible of those core dumps. They may be
occuring for multiple reasons/bugs.
