AFLplusplus: FRIDA mode for apache httpd result in a Segmentation fault
When I fuzz apache httpd-2.4.52 with AFL++ fride_mode, it result in a Segmentation fault:
So I debug it with command below:
The code return to a strange address belong to nobody. So I set a breakpoint before it crash and it shows that the dynamic library
mod_ssl.so load address changed from 0x7ffff357e000 to 0x7ffff0af2000.
I am wondering why the load address of the shared library changed at running of a process.

Yeah. Let’s keep the ticket open. If I get some time next week, I’ll have a look at the instrumented code and see if I can figure out what’s up. Might need @icytxw to test out a branch to see if it helps though.
