Hi!
With both GCC 12.2.0 (Debian), and GCC 13.0.1 20230315 (built from source),
I can reproduce these false positives.
The reproducer program is a small program that checks a password against a
hardcoded string, and conditionally prints "validated". I wrote it
precisely to demonstrate how [[gnu::malloc(deallocator)]] can be used to
ensure that passwords are not leaked in memory, but I found out that it
fails to detect some conditions.
Here's the program (it uses agetpass(), as defined in the shadow project):
$ cat pass.c
#include <err.h>
#include <errno.h>
#include <limits.h>
#include <readpassphrase.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#define PASS_MAX BUFSIZ - 1
#define MALLOCARRAY(n, type) ((type *) mallocarray(n, sizeof(type)))
[[gnu::malloc, gnu::malloc(free)]] void *mallocarray(size_t nmemb, size_t size);
void erase_pass(char *pass);
[[gnu::malloc(erase_pass)]] char *agetpass(const char *prompt);
void
do_work(void)
{
char *pass;
pass = agetpass("Enter your password: ");
if (pass == NULL)
err(EXIT_FAILURE, "agetpass");
if (strcmp(pass, "secret") == 0)
puts("validated");
/* erase_pass() zeroes the memory (think of memset(3), or bzero(3))
and then releases the memory to the system (think of free(3)).
If you only call free(pass), then you release the memory to the
system without zeroing it. Remember it contains a password!
We would be leaking a password into the system memory, which can
later be assigned to a different process.
So, we should call erase_pass() as soon as possible, but let's
say we forgot, and just call free():
*/
#if defined(BUG_1)
// We forgot to zero the memory.
free(pass);
// GCC correctly catches this as -Wmismatched-dealloc
#elif defined(BUG_2)
// We zeroed, but forgot to free(3).
bzero(pass, PASS_MAX + 2);
// GCC misses this.
#elif defined(BUG_3)
// We forgot both of them.
// GCC also misses this.
#else
erase_pass(pass); // OK, but 2 false positives.
#endif
}
int
main(void)
{
do_work();
for (;;)
sleep(1);
}

Maybe I'm missing something, but I don't think falanyzer is correct here.
Should I report this in bugzilla?
Cheers,

I very briefly tried to reproduce this myself, but I suspect we've got
different headers.

Quite possibly.

Yes please. Please can you attach the preprocessed source [1] to the
bug report(s) so that we're looking at the same code. Ideally also a
link to godbolt.org showing the issue.
Thanks
Dave

I'm on Debian Sid with libbsd-dev 0.11.7-4, and libc-dev 2.36-8.
Maybe that tells you something?

Will do.

Sure; it's attached to this mail. Produced with:
$ cc -Wall -Wextra pass.c $(pkgconf --cflags --libs libbsd-overlay) -fanalyzer -O3 -E > pass.c.i

I'm not very used to godbolt, sorry. If this email isn't enough for you,
I'll try godbolt.
