Hi,
The process being traced is written in C++ and the symbols are mangled
and we don't do any auto-demangling in Solaris. The demangled version of
the function looks like:
$ dem _Z12write_recordP3THDP8st_tableP12st_copy_info
_Z12write_recordP3THDP8st_tableP12st_copy_info == write_record(THD*,
st_table*, st_copy_info*)
If the application has been built with Sun Studio you can either
use dem(1) or pipe the lot through c++filt(1) to make it prettier.

I traced mysql using dtrace -n 'pid2218::my_malloc:entry{ustack()}',
the result looks the following,
For the line
mysqld`*_Z12*write_record*P3THDP8*st_table*P12*st_copy_info+0x53,
What's the meaning of _Z12, P3THDP8, P12? And why there are three
functions in that line (write_record, st_table,st_copy_info)?
