1. Phix 0.8.0 - running 'p' produces 'segment violation'

I have downloaded and installed the 64 bit version of phix for linux as per the instructions (i note that i did have to change the download of p32 to p64 - so i assume that is an error in the documentation that needs to be fixed). I am running Debian Buster (testing) with kernel 4.19.28 with all of the latest updates applied. When I try to do './p -test' it crashes with 'segment violation'. I note that there is not any debug information in the executable when I went into gdb to attempt to get a backtrace to provide further information here. Can someone please advise how I can progress this matter further ?

After changing the p32 to p64 as suggested above, the install tests ran correctly on Linux Mint 64. However, running the primes demo didn't:
irv@irv-desktop ~/phix/demo/rosetta $ ../../p Extensible_prime_generator.exw
The first 20 primes are: {2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71}
The primes between 100 and 150 are: {101,103,107,109,113,127,131,137,139,149}
There are 30 primes between 7700 and 8000.
The 10th prime is : 29
The 100th prime is : 541
The 1,000th prime is : 7919
The 10,000th prime is : 104729
The 100,000th prime is : 1299709
The 1,000,000th prime is : 15485863
The 10,000,000th prime is : 179424673
