[PATCH] elfint.c: Fix NULL pointer dereference issue in process_file function

[ant . v . moryakov]

From: AntonMoryakov <ant.v.morya...@gmail.com>

fix: fixed null pointer inference error in process_file function

Fixed a bug that could cause the program to crash when processing files without 
a suffix.
Added a NULL check for the suffix pointer before calling stpcpy().
