Easily:
1) download the tarball mentionned in the bug report and untar it
2) do 
CC=gcc-4.0 ./Configure
3) do 
make bench

One test-case fails (alglin).
Alternatively, you can do
make gp
./gp
matker([1,2;3,4])
  *** matker: bug in GP (Segmentation Fault), please report

More information about compiler options that fix this problem:

Not at that time, unfortunately. The bug only occurs inside deeply inlined
code.
