Bug ID: 110488
Summary: Legal deferred constant rejected
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: lo50goa3 at duck dot com
CC: dkm at gcc dot gnu.org
Target Milestone: ---
Created attachment 55429
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55429&action=edit
Minimal reproducer
Xubuntu 23.04 X86_64
GNAT 13 installed with
apt install gnat-13
Compiling the attached with
gnatmake -gnatc b_strings_prob.ads
gives
b_strings_prob.ads:11:04: error: subtype does not statically match deferred
declaration at line 4
gnatmake: "b_strings_prob.ads" compilation error
According to Randy Brukardt, ARG member and ARM editor, this is legal Ada and
should be accepted.
Output of
x86_64-linux-gnu-gcc-13 -v
Using built-in specs.
