Hello all,
When I start maxima, I get the following warning message:
The SGC segfault recovery test failed with memprotect_bad_fault_address, SGC
disabled
The SGC segfault recovery test failed with memprotect_bad_fault_address, SGC
disabled
Maxima 5.41.0 http://maxima.sourceforge.net
using Lisp GNU Common Lisp (GCL) GCL 2.6.12
Distributed under the GNU Public License. See the file COPYING.
Dedicated to the memory of William Schelter.
The function bug_report() provides bug reporting information.
Actually I encountered this problem quite a while ago after an update,
but I didn't report it since it was not fetal.
Does anyone knows what's going on?
Cheers,
Alex

Thank you! The patch works, the warning has gone. I am closing this bug.
