![]() ![]() ![]() I don't believe OSes provide these privileges after the program in question is started. If those hooks aren't provided at the time of program start, the heap checkers cannot leverage them. Heap checking usually requires elevated privileges, or hooks, to be provided by the operating system.This is because they watch to make sure each allocation has a corresponding deallocation, and they would miss some otherwise. Some offer the ability to tweak the exact timing, but the environment variables that start them must be set when the program runs. Heap checkers initialize when the program begins.I think without providing support for allocation monitoring after program start directly in the source code, you're out of luck. You get readable form where you can locate those strings into Now, use strings command or hexdump -C to print the dump_outputfile.dump strings outputfile.dump I used gdb on running process to dump the memory to some file. Use GDB to dump memory on running process or get the coredump using gcore -o process VmFlags: rd wr mr mw me ac VmFlags: rd wr mr mw me ac KernelPageSize: 4 kB KernelPageSize: 4 kB Private_Dirty: 28 kB Private_Dirty: 36 kBĪnonymous: 28 kB Anonymous: 36 kB #INCREASE MEM capture again /proc/PID/smaps and save it has afterMemInc.txtįind the difference between first smaps and 2nd smaps, e. ![]() ps -auxĬapture the /proc/PID/smaps and save into some file like BeforeMemInc.txt.
