Enable a breakpoint only after another event has occurred. For example, if your program begins to execute incorrectly in function hash, but only after the 1300’th symbol lookup, you would type:
(dbx) when in lookup -count 1300 { stop in hash hash_bpt=$newhandlerid when proc_gone -temp { delete $hash_bpt; } } |
$newhandlerid is referring to the just executed stop incommand.
