Edit: It works now. Seems the value table for the complex RNG was never initialized. Don't ask why, don't know either ...
Huh, this is frustrating. I'm trying to get a 2001-era variant running, and i'm getting similar symptoms. You found a problem but don't explain what you changed.

I think psi-angband is based on 2.9.x, and keeps hanging in z-rand, but I'm not sure why.

I can see in a debugger that Rand_state has stuff in it....

Hmm, in my case the problem was:

* the values are defined as u32b.
* However, they were 64bit
* The loop only escapes if the values are below a threshold based on 32 bit values, so the loop will last 4 billion times longer than intended.
* Using the define L64 worked (which was intended for DEC alpha) which used unsigned and signed int instead of 'long' for u32 etc.
* In practice, this means I added -D"L64" to the compiler flags in Makefile.std.

The original symptom was a parse problem in the info files, because the code assumes the memory will fit, but is using 8-byte integers instead of 4-byte, which overflows the zeroed memory space.
