jemalloc_ptr_info takes an outparam, which makes it harder to use in a
debugger: you'd need to find some memory to use as outparam and pass
that in.
So for convenience, we add a non-exported symbol for use in debuggers,
which just returns a pointer to a static buffer for the result.
lldb:
(lldb) print *Debug::jemalloc_ptr_info($0)
(jemalloc_ptr_info_t) $1 = (tag = TagLiveSmall, addr=0x000000011841dd80, size = 160)
gdb:
(gdb) print *Debug::jemalloc_ptr_info($0)
$1 = {tag = TagLiveSmall, addr = 0x7f8e7ebd0dc0, size = 96}
windbg:
0:040> .call Debug::jemalloc_ptr_info(0x6187880)
Thread is set up for call, 'g' will execute.
WARNING: This can have serious side-effects,
including deadlocks and corruption of the debuggee.
0:040> g
.call returns:
struct jemalloc_ptr_info_t * 0x7501f3f4
+0x000 tag : 1 ( TagLiveSmall )
+0x004 addr : 0x06187880 Void
