Summary: System gdb produces an error when attaching to files
built with -g
Product: Base System
Version: 10.3-RELEASE
Hardware: i386
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: gnu

I built vi from /usr/src/usr.bin/vi with CFLAGS=-g for debugging purposes.
When attaching the gdb included with the system to a vi-process, however, I get
the following error:
