afl-cc afl-proxy.c -> ld error

[sk3pta]

Hi,

I tried to compile afl-proxy and got this.

❯ ../../afl-cc -I../../include/  -o afl-proxy afl-proxy.c

afl-cc++4.09a by Michal Zalewski, Laszlo Szekeres, Marc Heuse - mode: GCC_PLUGIN-DEFAULT
afl-gcc-pass ++4.09a by <oliva@adacore.com>

/usr/bin/ld: ../../afl-compiler-rt.o: error adding symbols: bad value

I looked into afl-compiler-rt.o.c and then changed __thread u32 __afl_map_size to u32 __afl_map_size.
But I can not understand what can I do with multiple definitions of __afl_area_ptr and __afl_map_size
Thanks in advance!
