tcmalloc not auto detected while upgraded to 16.3 from 12.1

[fish2bird]

Describe the bug

Same coredump with tcmalloc, previous version can detect and heap /v as expected

but new core_analyzer failed.

(gdb) heap /v
Failed to extract heap metadata from gv mp_
==================================================================================
== The memory manager is assumed to be glibc 2.34                                ==
== If this is not true, please debug with another machine with matching glibc   ==
==================================================================================
failed to init heap

after switch_heap tc， all comes back

(gdb) switch_heap tc
switch to heap tc

(gdb) heap /v
  size_class   num_spans  block_size  inuse_blks inuse_bytes   free_blks  free_bytes

To Reproduce Steps to reproduce the behavior:

Expected behavior

detect tcmalloc

Screenshots

Desktop (please complete the following information):

• OS : EulerOS V2R12
• tcmalloc = gperftools 4.5.10
• libc = 2.34
• all debug symbol loaded
• gdb 16.3

Additional context

I debugged new version, found out lookup_symbol("TCMalloc_PageMap2<35>", 0, VAR_DOMAIN, 0).symbol got nullptr

but gdb 12.1 returns valid symbol ptr.
