Newbie question - gcry_sexp_build Seg. Fault

[António Pinto]

Hello again,

Problem solved, I recoded the app from scratch and I don't have the
problem anymore.
The problem was probably related to the fact that I was using (badly)
some symmetic encryption gcrypt routines in another part of the
program.

Thanks for the help.
