Hi,
I found some a regression bug.
This is anInvalid Address Deference bug, in handle_elf function in
/src/strip.c.
This problem exists in elfutils-0.176, but cannot reproduce in elfutils-0.175.
Thus this is a regression bug. elfutils 0.175 is right.
Here are the POC files. Please use " ./eu-strip $POC " to reproduce this
