libmallocTrace

A tool for tracking memory allocation based ld-preload

• how to build

  make
  cd example && make
  

• how to use

  a simple way is to execute something like below :

  LD_PRELOAD=/you_path/libmTrace.so /you_path/application

  such as:

  cd example && make
  LD_PRELOAD=../libmTrace.so ./example
  

  Run example generate trace log. You can see appliaction invoke malloc/free/new/delete backtrace.

  ... 
  
  malloc (247) returned @0x418590
  [backtrace]
  ../libmTrace.so(_Z14printBacktracev+0x2b) [0x7ffff7fd9370]
  ../libmTrace.so(+0x146c) [0x7ffff7fd946c]
  ./example(_Z7notleaki+0x31) [0x401287]
  ./example(main+0x7f) [0x401382]
  /lib64/libc.so.6(__libc_start_main+0xf3) [0x7ffff71066a3]
  ./example(_start+0x2e) [0x40110e]
  
  
  freed pointer @0x418590
  [backtrace]
  ../libmTrace.so(_Z14printBacktracev+0x2b) [0x7ffff7fd9370]
  ../libmTrace.so(+0x14d8) [0x7ffff7fd94d8]
  ./example(_Z7notleaki+0x58) [0x4012ae]
  ./example(main+0x7f) [0x401382]
  /lib64/libc.so.6(__libc_start_main+0xf3) [0x7ffff71066a3]
  ./example(_start+0x2e) [0x40110e]
