Bug ID: 17417
Summary: debug info mismatch warning printed four times
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: dje at google dot com
I happened to update my fc20 system without updating the debug info for some
libraries, and stumbled upon this.
The first instance is gdb looking in /usr/lib/debug/lib64.
The other three instances are /usr/lib/debug/usr/lib64, but with an extra "/"
moving about. I haven't root-caused why, but gdb should be a little smarter
... a typical user would find this disappointing.
