Hi,
The issue seems to be related to the security features of grsecurity/PaX, which are designed to enhance system security by preventing certain types of memory exploits. This can sometimes interfere with applications that need to mark memory pages as executable. You should either disable grsecurity/PaX if you do not need it, or use “paxctl” tool to modify the PaX flags on your executable. Are you using your own kernel where the grsecurity/PaX is enabled?
