Memory leaks and access to uninitialized memory #51
Description
The cause can be specified as two things below.
- Memory allocated in ptext_load_file function is not freed
- The padding area of the local variable key of the pgspHashKey structure of the pgsp_store function is included in the calculation of the hash value. (fix initialization of pgspHashKey structure #40)
The above case may cause continuous memory growth of the backend process.
The cases below cause the same query and plan to produce multiple result records.
There is already a fixed code for this issue.
Can I send you a Pull-Request?
I've attached the valgrind report below.
