segmentation fault

[DeamLake]

when I run
untracer-afl -i in -o out -- ./size
It tells me that
segmentation fault
how can I fix it?
thx

size was from binutils
I make it by untracer-clang

More than likely this is due to the binary being compiled with untracer-clang as PIE instead of the required non-PIE. You can usually fix this by editing the buildall.sh in FoRTE-FuzzBench to add -no-pie to passToAs, e.g.:

compiler="/path/to/untracer-clang"
compilerXX="/path/to/untracer-clang++"
passToAS="-no-pie"

I'll add a couple of checks to UnTracer to try and detect when this happens.

Closing as it seems to be resolved.
