Segmentation fault (core dumped)

$./script: Segmentation fault (core dumped)

Analysis

The process tried to access a memory segment that it doesn't have permission to access (e.g., writing to read-only memory, dereferencing a null pointer).

Common Triggers

  • Dereferencing a null pointer in C/C++.
  • Stack overflow (infinite recursion).
  • Buffer overflow.

Debug Checks

  • $Debug with gdb ./program core.

Resolution

1
Fix the bug in the code (null check, array bounds).
2
Update the software if it's a third-party tool.
