            Bug ID: 119528
           Summary: __attribute__((deprecated(text)) triggers with
                    __attribute__((malloc(deallocator, index)))
           Product: gcc
           Version: 14.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: akallabeth+gnu at posteo dot net
  Target Milestone: ---

Got the following (deprecated) pair of allocator/deallocators declared in a
header:

__attribute__((deprecated("deprecated")) void free_foo(FOO* var);
__attribute__((deprecated("deprecated")) __attribute__((malloc(free_foo, 1)))
FOO* create_foo(void);

now this alone is enough to trigger deprecation warnings during a compile every
time the header is included.
looks like `GCC` considers the __attribute__((malloc(free_foo, 1))) as usage of
free_foo

for comparison, tried to compile the same with clang (19.7.1) and there there
are no warnings emitted.
