Great!  How?

From what I can see, the changes are:

   http://trac.macports.org/changeset/128721

Lawrence, is that all?

This is due to a cflag mismatch.  For example, on Debian, by policy, gcl
is built with

"gcc -c -fstack-protector-strong -Wformat -Werror=format-security
-D_FORTIFY_SOURCE=2  -Wall -fsigned-char -Wno-unused-but-set-variable
-pipe "

All modules (to be loaded) should be built with the same flags.  My
guess here is that the module had the stack protector, but not the
default gcl build.

OK; so if I understand correctly, you would recommend that Macports adds

 

   -fstack-protector-strong -D_FORTIFY_SOURCE=2

to its portfile for  GCL's?
