Subject: [Bug exp/26875] Incorrect value printed for address of first element of zero-length array
Date: Sat, 14 Nov 2020 12:04:58 +0000 [thread overview]
Message-ID: <bug-26875-4717-Ppp8TcAprC@http.sourceware.org/bugzilla/> (raw)
In-Reply-To: <bug-26875-4717@http.sourceware.org/bugzilla/>

--- Comment #6 from Tom de Vries <vries at gcc dot gnu.org> ---
The simplest fix would be to make sure get_discrete_bounds always returns
defined *lowp and *highp:
...
diff --git a/gdb/gdbtypes.c b/gdb/gdbtypes.c
index 686edafcf64..9a891e7bfde 100644
--- a/gdb/gdbtypes.c
+++ b/gdb/gdbtypes.c
@@ -1043,6 +1043,8 @@ has_static_range (const struct range_bounds *bounds)
int
get_discrete_bounds (struct type *type, LONGEST *lowp, LONGEST *highp)
{
+ *lowp = 0;
+ *highp = -1;
type = check_typedef (type);
switch (type->code ())
{
...
which also happens to fix PR26870 - "[fortran] Printing dynamic array fails".
