Hi Tom,

I see the above failure for both aarch64-linux-gnu and arm-linux-gnueabihf in our testing.  The log shows ([1]):
===
Breakpoint 1, storage () at /home/tcwg-buildslave/workspace/tcwg_gnu_2/gdb/gdb/testsuite/gdb.ada/scalar_storage/storage.adb:53
53	   Do_Nothing (V_LE'Address);  --  START
(gdb) print V_LE
$1 = (value => 126, another_value => 12, color => green)
(gdb) PASS: gdb.ada/scalar_storage.exp: print V_LE
get_compiler_info: gcc-14-0-1
print V_BE
$2 = (value => 126, another_value => 12, color => red)
(gdb) FAIL: gdb.ada/scalar_storage.exp: print V_BE
===

Any idea what can be causing this?

This failure happens in CI configurations where we track tip-of-trunk GCC.
