TrueCrypt is a complicated application and even the truecrypt -h output is a chore to read. You will probably find it helpful anyway.

Further information that would be good to know...

  • How does the process respond to signals e.g. INTR and HUP noting any interesting results
  • Take a core dump using SIGABRT and run strings -a against the coredump, plus a backtrace
  • Use elfdump and ldd to show the ELF signatures and shared library (.so) linkages
