I want to alter a ELF executable function call and replace one of it's parameters.The executable calls dlopen() function and passes RTLD_NOW as the flag parameter.I want to change it to RTLD_LAZY.What's the easiest way to detect the exact place where this call is done, and replacing the parameter.I have to do it on production environment, so I only have GNU toolchain, gcc, gdb, etc.
