Find the solution:

lldb-11 tests_curl
(lldb) target create "tests_curl"
Current executable set to 'tests_curl' (i686).
(lldb) image lookup --address 0x005e34a9
  Address: tests_curl[0x005e34a9] (tests_curl..text + 1975465)

Need help to find source file location by PC address

2020-12-12 Thread Calvin P via Digitalmars-d-learn 
I made a cross build with LDC -g -gdwarf-4 -O0 -D_DEBUG, the app 
crash with a report include PC address 0x005e34a9.


Is there a way to find the source location for that PC address?
