[Mod-security-developers] unrecognized command line option ‘-fsanitize-coverage=4’

[Ervin H. <ai...@gm...>]

Hi there,

I'm playing with ModSecurity 3, and try to build first with all
available features.

I've installed all necessary libraries, and gave:

./configure --with-lmdb --enable-parser-generation --enable-mutex-on-pm --enable-afl-fuzz

then

export CXX=afl-clang-fast++ 
export CC=afl-clang-fast 


and

make.

I'm using GNU GCC - tried with different versions:
* gcc version 7.2.0
* gcc version 6.3.0
* gcc version 4.9.2


but none of above supports the option "-fsanitize-coverage=4".

I've read the GCC documantation here:

https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html

but looks like GCC doesn't support this option, only the

-fsanitize-coverage=trace-pc

and

-fsanitize-coverage=trace-cmp

Which C compiler supports the original option?


Thanks,


a.
