Add an accompanying option to the 'frame variable -w' command to, instead of watching the variable, watch the location pointed to by the variable. An example, (lldb) frame variable -w write -x 1 -g g_char_ptr (char *) g_char_ptr = 0x0000000100100860 ""... Watchpoint created: WatchpointLocation 1: addr = 0x100100860 size = 1 state = enabled type = w declare @ '/Volumes/data/lldb/svn/trunk/test/functionalities/watchpoint/hello_watchlocation/main.cpp:21' ...
