Floating point exception (core dumped) #3

I'm getting a weird error with a 3.5MB database file, only on some machines. It works on my WSL Ubuntu instance, and on Windows, but not on my native Ubuntu VPS.

This looks like a Blosc error. Could you try something like this:

from blosc2 import decompress

with open("path/to/db/file", "rb") as db_file:
    data = decompress(db_file.read())

    # let's just print the first 1000 chars, we don't need the entire file.
    print(data[:1000])

Try it both on the working machines as the VPS. If this has the same behaviour then you should probably create an Issue on the blosc2 repo.

Works on the working machines.

Doesn't work on the faulty machine.

Will report to blosc.
