And it may also affect other tools. Valgrind's DWARF reader was written based on GCC's output, which I assume is tuned for GDB. There are already a few limitations with clang's emitted DWARF. That has been improving, but there is still a bit lacking regarding local variables (possibly a limitation of the Valgrind DWARF reader, it's not part of the code that I've worked on much). I have no experience with changing that setting but I guess that it could have an impact. A+ Paul
