How to know which file(s) were opened by a process at the time of crash?

Hi experts,

  Does anyone knows, given a process core dump, how I can get the list of files were opened by this particular process at the time of crash? For example,

[sbpsvrwm321] # mdb core_sbpsvrwm321_rwsrv_11235_8320_1387466542_18032
