Hi Mingi,
Thanks for the bug report. I was unable to reproduce the exact failure
that you reported, but I did find something similar. The patch you have
supplied does help, but I also found that there was a problem trying to
read a 64-bit LEB128-encoded value into a 32-bit variable. So I have
extended the patch to cover that.
Cheers
Nick
PS. You might find it interesting to create some test binaries with very
large LEB128 values in them (more than 128 bits say) and see how the
various tools in the binutils suite cope with them.
