Package: afl++
Version: 4.04c-3
Severity: normal
Hello,
When trying to use "afl-clang -m32" on amd64, it fails, even though
clang itself supports -m32:
$ clang -m32 hello.c -o hello
$ ./hello
hello
$ afl-clang -m32 hello.c -o hello
afl-cc++4.04c by Michal Zalewski, Laszlo Szekeres, Marc Heuse - mode:
LLVM-PCGUARD
[-] PROGRAM ABORT : -m32 is not supported by your compiler
Location : edit_params(), src/afl-cc.c:1217
$
Strace reveals that the error happens after afl-clang fails to find
afl-compiler-rt-32.o:
access("/usr/bin/../lib/afl//afl-compiler-rt-32.o", R_OK) = -1 ENOENT (No such
file or directory)
Inclusion of afl-compiler-rt-32.o in amd64 builds of afl++ would be useful
because -m32 helps in certain fuzzing scenarios (using AddressSanitizer plus a
virtual memory limit).
Best regards,
jn
