I’m seeing an “Illegal Instruction” fault and don’t quite know how to
generate a proper bug report yet.
This is the compiler:

Using built-in specs.

--enable-checking=release

Can someone suggest a way forward?
Please could you raise a PR (Bugzilla) -
(https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc)
.. the information here is enough to start
- but it would help to know what you were compiling when this occurred ..
adding ‘-save-temps’ to the compile line and adding the .i file to the BZ can
be helfpul.
.. I think this will take a little analysis (and isn’t something I've seen
in testing on either i7 or xeon w hardware).
thanks
