Is this a bug in gdb

Hello,

The help text of the watch command claims that the -l option watches the
memory of the variable. When I tried this, I was surprised by the
outcome (reproducible):


(gdb) watch this->v_
Hardware watchpoint 2: this->v_
(gdb) watch -l this->v_
A syntax error in expression, near `restrict *) 0x00007fffffffd398'.
(gdb)

Note: Using print &(this->v_) and  watch (char[8])
*outputoftheprintcommand worked.


I am asking you whether this is a bug in gdb or not, because if it is a
bug in gdb, I will try to make a minimal example an file a bug report.


Greetings
