The file guile/src/core.c contains code that manipulates the scm_t_port
structure, which is defined by Guile and contains off_t fields. So the
gnutls-guile code thinks scm_t_port is 120-byte whereas libguile thinks
it’s 96-byte long, and more generally they use different field offsets.
The code that uses scm_t_port in gnutls-guile relates to the “session
record port” (info "(gnutls-guile) Input and Output").
