The compiler crashes processing an empty aggregate initializing
a component of a discriminated record type using the Ada 2022
notation (that is, []).
gcc/ada/
* exp_aggr.adb (Build_Record_Aggr_Code): Protect access to
aggregate components when the aggregate is empty.
Tested on x86_64-pc-linux-gnu, committed on master.
