Dear GAP-Forum,

This is to announce a bugfix for the GAP library. The priority
of this fix is high. You should apply this fix soon.

This fix corrects:
1) A potential 'division by zero' error in the polynomial factorization
routine over Z when trying to reduce coefficients.
2) A wrong result of 'IsSubset' for FpGroups if the FpGroup already contains
3) A missing record component, leading to a syntax error, in the element
conjugacy test for matrix groups.

Errors 1 and 3 will yield GAP to enter the 'brk' loop, error 2 may yield
wrong results!

Thanks to Gunter Malle for pointing out the errors 1 and 3.

To apply the fix, load the zoo archive 'fix2.zoo' from the
bugfixes web page
Alternatively you can find this file in the 'bugfixes' directory of the
GAP ftp distribution.

Unpack the file in the home directory of your GAP distribution (the
directory containing the 'lib' and 'etc' directories) using 'unzoo'. This
will replace the erraneous files by fixed versions.

You can remove the file 'description2' afterwards.

You won't need to recompile anything.

Best regards,

Alexander Hulpke
