[GAP Forum] GAP crashes when reading a syntax error

[Nicholas Loughlin]

Hi forum,

I tested this on my macbook (versioning below) and couldn't replicate the bug.
GAP4, Version: 4.4.12 of 17-Dec-2008, i686-apple-darwin9.6.0-gcc

Also couldn't replicate on my linux box, which runs Ubuntu 10.04.4 LTS:
GAP4, Version: 4.4.12 of 17-Dec-2008, i486-pc-linux-gnu-i486-linux-gnu-gcc

The bug may be specific to later editions of ubuntu and/or GAP?

Hope this is helpful,
Nick Loughlin

Subject: [GAP Forum] GAP crashes when reading a syntax error

Dear GAP forum,

I'm running GAP 4.5.5 on Ubuntu 12.04.  When I read a file into GAP with the following contents:

f:=function()
local k;
for k in [1] do Print(k));od;
end;

GAP unexpectedly closes.  (This happens on both my machines.)  Of course, there is a syntax error in the third line, but it's surprising to me that this causes GAP to crash.  Is this a problem with GAP, or have I got something set up badly?
