sx1302_hal's packet forwarder facing Segmentation Fault with Raspberry Pi (OpenWRT OS) + Semtech LoRa Corecell interface board via USB interface

I'm using a Raspberry Pi 3B+ board with OpenWRT OS (v23.05.2) and trying to use a Semtech SX1302 LoRa Corecell interface board via USB interface to use them as a LoRa Gateway setup (RPi + Semtech SX1302).

While using the sx1302_hal's Lora packet forwarder, it always ends up in segmentation fault when reaching the uplink thread thread_up()

Segmentation fault

My Observations:

It seems it is having trouble using the buff_up of the thread_up ()
The same setup is working fine with Debian OS. only with OpenWRT, I'm facing this issue.

The library files libpthread.a, librt.a in openwrt doesn't seem to be valid after installed via opkg install as far as I have noticed. for e.g.,

root@OpenWrt:~/sx1302_hal/bin# find / -name libpthread.a
/root/SDK/openwrt-sdk-armsr-armv7_gcc-12.3.0_musl_eabi.Linux-x86_64/staging_dir/toolchain-arm_cortex-a15+neon-vfpv4_gcc-12.3.0_musl_eabi/lib/libpthread.a
