- [ ] **mbedtls**

|
```

*Edit:* This seems to have been handled upstream by silencing the GCC warning already.
```c
/* mbedtls_sha512_finish_ret's output parameter is declared as a
* 64-byte buffer, but since we're using SHA-384, we know that the
* output fits in 48 bytes. This is correct C, but GCC 11.1 warns
* about it.
*/
#if defined(__GNUC__) && __GNUC__ >= 11
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wstringop-overflow"
#endif
mbedtls_sha512_finish_ret(&sha512, padbuf);
#if defined(__GNUC__) && __GNUC__ >= 11
#pragma GCC diagnostic pop
#endif
```
But this doesn't work during LTO linking due to a GCC bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80922

This is related to #50910 which we'll keep that old one focused on the `3.x` branch.

### Steps to reproduce

- `scons production=yes`

### Minimal reproduction project (MRP)

n/a

Reproduce the warnings with `scons production=yes` on the reported Fedora/GCC setup, then inspect the affected paths under `thirdparty/`, including `clipper2`, `freetype`, `glslang`, `icu4c`, `libktx`, `noise`, and `vhacd`. Use the referenced issues such as #88508, #88526, and #88659 to determine the intended scope; done would require resolving or appropriately handling the listed LTO warnings.
