Hi Alexandre,
Thanks for reporting this bug.
This was a problem in the DWARF parser where it was reading a 64-bit
value and then only checking the bottom 32-bits to see if they were in
range! I have applied a fairly large patch to fix this problem, and
catch others like it in the future.
Cheers
Nick
