Comment #7 on issue 3851 by [email protected]: Can not print stack trace
info when debug V8 sample code shell.cc with GDB
https://code.google.com/p/v8/issues/detail?id=3851
I have noticed you are trying to use --gdbjit. You need to pass
--gdbjit-full to allow backtracing otherwise V8 only emits debug info for
code objects with line information (normal JS functions). Which means GDB
can't unwind past code stubs. GDB on x64 relies on .eh_frame for stack
unwinding.
Maybe we should kill gdbjit_full or make --gdbjit imply --gdbjit_full?
