My compiled code is faulty and I decided to use address sanitizer to find its problem with g++ and options -Og -g3 -fsanitize=address -fno-omit-frame-pointer.
I used llvm-symbolizer
export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer-9
$ ASAN_OPTIONS=symbolize=1 ./a.out
AddressSanitizer:DEADLYSIGNAL
=================================================================
==7296==ERROR: AddressSanitizer: SEGV on unknown address 0x000200000039 (pc 0x000200000039 bp 0x000000000001 sp 0x7ffd2b566c48 T0)
==7296==The signal is caused by a READ memory access.
==7296==Hint: PC is at a non-executable region. Maybe a wild jump?
AddressSanitizer:DEADLYSIGNAL
AddressSanitizer: nested bug in the same thread, aborting.
It has no meaningful information that helps me finding the source of the problem in my code
It does not dump the stack trace. What does it mean and how can I find the stack-trace or the location of the dumped addresses?
update: Using gdb does not give much more info too
(gdb) run
