it would be nice to have more information available in case of ICE;
Like -

* (Symbolic) Stack traceback
* Source code location
* Data structures

The ice for Ada front end already provides this information. Even saying what
to attachments are required.


The c/c++ frontend ice says to rerun with -freport-bug and attach that .out
file.

What more improvements are needed to compared to what clang does?
Outputting internal state is hard to do really and confuse everyone.

Right, including the chain of instances for the source location.

I agree, and neither a backtrace nor a snapshot of data structures are
sufficient to diagnose the problem in most cases, the compiler is much too
complex for this.
