Bug#1115881: glibc 2.42 breaks the gnat-XXX provide
Package: src:glibc
Version: 2.42-2
Severity: serious
Tags: sid forky
X-Debbugs-CC: debian-ada@lists.debian.org
Affects: src:gcc-14
When gcc-14 is rebuilt with glibc 2.42, the gnat provides will change. I
figured out this is due to:

---------------------------------
-- Terminal control characters --
Now, that might not be considered an ABI break for glibc, but the
checksum over the .ali files interpret that as such one. However that
seems to be the first time that a glibc update changes that gnat ABI.
Note, that we just can rebuild all the packages build-depending on
gnat/gnat-14, but maybe the current ali checksum approach is too tight
to be useful for an ABI check.
