Summary: Fail to restore breakpoints on static functions with
namespace
Product: gdb
Version: 7.2
Status: NEW
Severity: normal
Priority: P2
Component: c++
AssignedTo: unassigned@sourceware.org
ReportedBy: stephane.chauveau@caps-entreprise.com
Created attachment 5714

Code sample
A breakpoint set on a static function within a namespace is automatically
qualified with the filename. For example, for the static function xxx::fun2()
in the file main.cc , the breakpoint description becomes
main.cc:xxx::fun2
Unfortunately, gdb fails to parse that syntax and so cannot restore those
breakpoints after a 'run'
The attached file provides a small example.
Breakpoints can be successfully set on both the global function xxx::fun1 and
the static function xxx::fun2
# (gdb) break main
# Breakpoint 1 at 0x4005bc: file main.cc, line 20.
# (gdb) run
# 20 xxx::fun1() ;
# (gdb) break xxx::fun1
# Breakpoint 2 at 0x40059c: file main.cc, line 9.
# (gdb) break xxx::fun2
# Breakpoint 3 at 0x4005ac: file main.cc, line 13.
# (gdb) cont
# Breakpoint 2, xxx::fun1 () at main.cc:9
# (gdb) cont
# Breakpoint 3, xxx::fun2 () at main.cc:13
# (gdb) cont
# Program exited normally.
However, gdb fails to restore the breakpoint on xxx::fun2 when the process is
restarted:
# (gdb) run
# Starting program: /udd/schauvea/GDB/a.out
# Error in re-setting breakpoint 3: Can't find member of namespace, class, #
struct, or union named "main.cc:xxx::fun2"
# Hint: try 'main.cc:xxx::fun2<TAB> or 'main.cc:xxx::fun2<ESC-?>
# (Note leading single quote.)
#
# Breakpoint 1, main () at main.cc:20
# 20 xxx::fun1() ;
The new command 'save breakpoints' shows that the breakpoint description is
main.cc:xxx::fun2 which is not accepted by gdb:
# (gdb) save breakpoints /dev/stdout
# break main
# break xxx::fun1
# break main.cc:xxx::fun2
# disable
# Saved to file '/dev/stdout'.
