ESP32-S3 Posix FILE SYSTEM APIs crashing regardless LIBC implementation

[alespitfire]

Hello,
I am trying without any success to have POSIX library working with file system API.
In particular I need fopen, fread, fwrite and fstat.
I am working with the ESP32-S3 as mcu connected to an SD card.
I have no constraints about Zephyr version. I have no constraints about file system (but a preference for FATFS).

I have tried to readjust the fs_sample to use the posix functions to read from files but I fail, the system crashes.
(look at the attached file main.c function void test_posix(const char *path) L.125)

fs_sample.zip

I suspect the issue is in the libc or posix implementation as the fs_sample based on Zephyr File System works flawlessly.
In addition without expliciting which libc the compiler should use, the system does not crash; instead by adding CONFIG_NEWLIB_LIBC=y or CONFIG_PICOLIBC_USE_MODULE=y the system crashes.

Can you help me to figure this out?

Thank you
