#5 memory allocation/deallocation

[Anonymous]

In many places at code is allocated memory, which is not
deallocated.
for example in book_parse_sheets, there is a line
r = record_get(book); in record_get there is a memory
allocation for the record, but later nowhere (just I didn't
found the place where) the memory is freed, this would lead
to a memmory leaks.
