I had the same same setup (files on NAS in local network) earlier on Gentoo, darktable was on version 5.2.x

I am thinking on teh calculations done the rdd.c file, since the segmentation fault stops there: 

Thread 6 received signal SIGSEGV, Segmentation fault.
[Switching to thread 478363 of process 16229]
0x00000ad90d910d52 in rcd_ppg_border (out=0x0, in=0xad99ebbe000, width=<optimized out>, height=2865, 
    filters=2492765332, margin=7) at /usr/ports/pobj/darktable-4.8.1/darktable-4.8.1/src/iop/demosaicing/rcd.c:122
122               out[4 * ((size_t)j * width + i) + c] = fmaxf(0.0f, in[(size_t)j * width + i]);

Is it posisble that cc is using another size of 'const int with' then gcc under linux and with that the index for the scalar out[] is outside of assigned menory?
