Null pointer acces / segfault in util-has.bs

[StringEpsilon]

Compiled with FreeBASIC Compiler - Version 1.05.0 (11-01-2015), built for linux-x86_64 (64bit).

I get a null-pointer access on line 53 in util-hash.bas

==5959== Command: ./fbfrog
==5959== 

Aborting due to runtime error 7 (null pointer access) at line 53 of util-hash.bas::GROWTABLE()

Fixing that by checking "item" for being 0, I get this:

==6959== Command: ./fbfrog
==6959==

I tried writing a fix, but since I don't fully understand your code and the obvious did not work, I feared I might do more harm than good.

Hi,

this should be fixed by commit 0c9ac2e1d24b5215418efcf9ab16118d5d7bb5ed now.

There was a problem in the fbkeywords code, but it only showed up if compiling with fbc -gen gcc (for example 64bit). Thanks for reporting it.
