gprbuild V22.0.0 creates backtrace on incorrect input instead of error message

[RREE]

calling gprbuild on the attached gpr-files creates a backtrace. Expand bug.tar.gz and go into AVRAda_Examples:

gprbuild 18.0w (standard Debian version) gives a friendlier message, but still not very helpful:

gprbuild -s -j0 -p -P 7seg/seven_segment_disp.gpr
gprbuild: raised CONSTRAINT_ERROR : gpr-names.adb:231 range check failed

The crash is of course not expected, but the project is illegal: for Runtime ("Ada") use Avrada_Rts.Runtime; - there is no variable Runtime defined in Avrada_Rts. Probably what was intended is an attribute reference, something like for Runtime use Avrada_Rts'Runtime;

(edit: the crash is due to an import of a missing file "mcu.gpr")

[RREE]

Yes, the intend was to use an attribure reference. But a simple misunderstanding or typing error (. <--> ') or (as you have already found, thanks) a missing with should not cause a crash. That's why the issue title contains "... on incorrect input ...".

BTW, the file mcu.gpr is present in my case. I probably missed to send it in the bug report.

(edit - never mind, I got my wires crossed)

For the records, I get the same error when calling --show-targets:

$ gprconfig --show-targets
raised CONSTRAINT_ERROR : gpr-names.adb:231 range check failed

on this gprbuild version:

$ gprbuild --version
