This should be 'struct stab *psTab' to declare a pointer to the struct

The parameter to g_malloc() should be 'sizeof(struct stab)', so it
allocates enough memory for the struct (rather than just a pointer to it).

The checks for NULL are not necessary for g_malloc() and friends because
they will bomb for you on error.

Hope this helps
