I also try to work with gdb and efence but it does not seems to work: I re-link LVM (with -O2) tools with libefence then launch gdb. At gdb prompt I type in "set environment LD_PRELOAD=libefence.so.0.0" then "run". But the message of the load of efence does not appears? And run failled on Segmentation fault without any diagnostic of efence. I think it is not the right way to work: if in command line I do "export LD_PRELOAD=libefence.so.0.0" then launch "mkdir toto" the message of efence load appears well?
Does it exist some where some HOWTO explaining the actual way to use efence?
