Bug ID: 23353
Summary: detect and warn about System Integrity Protection
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
Target Milestone: ---

On recent macOS (I'm using 10.13.5), the System Integrity Protection feature
prevents the debugging of certain executables.
For example, "gdb /bin/ls" will not be able to "run".

It would be good to detect this situation and tell the user what is
happening. Currently just a mysterious error message is printed.
