Bug ID: 112979
Summary: [13/14 regression] Gnat Bug Detected with Invalid
Prefix
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: suratiamol at gmail dot com
CC: dkm at gcc dot gnu.org
Target Milestone: ---
Created attachment 56861
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=56861&action=edit
Reproducer: to be gnatchopped
On running the code at [1], the gnat 13.2 compiler raises an error
about invalid prefix, which looks okay.
But the gnat trunk compiler causes a "Gnat Bug Detected", as seen
at [2].
Part of the message:
14.0.0 20231212 (experimental) (x86_64-linux-gnu) \
Assert_Failure failed precondition from einfo-entities.ads:2256|
A search on bugzilla for 'einfo-entities.ads' turned up empty.
The sources are also attached as a single .ada file.

--- Comment #1 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
That's because the trunk is built with assertions, in other words the GCC 14
compiler will behave as GCC 13 when it is released.
