Compilation warning in sqlite3-binding.c

Description
I encountered a compilation warning while attempting to build the github.com/mattn/go-sqlite3 package. The warning message is related to the sqlite3-binding.c file, specifically within the sqlite3SelectNew function. The warning suggests that the function may be returning the address of a local variable, which can lead to undefined behavior.

Steps to Reproduce
Clone the github.com/mattn/go-sqlite3 repository.
Build the package using the go build command.
Observe the compilation warning displayed.
Expected Behavior
The package should compile without any warnings, ensuring that there are no potential issues or undefined behavior within the code.

Actual Behavior
During compilation, the following warning is displayed:

sqlite3-binding.c: In function ‘sqlite3SelectNew’:
sqlite3-binding.c:128049:10: warning: function may return address of local variable [-Wreturn-local-addr]
128049 | return pNew;
| ^~~~
sqlite3-binding.c:128009:10: note: declared here
128009 | Select standin;
| ^~~~~~~
Environment
Go version: [Specify your Go version]
Operating System: [Specify your OS]
Additional Information
[Provide any additional information or context that may be relevant to the issue.]

Impact
The warning may indicate a potential issue in the code, where the function sqlite3SelectNew in sqlite3-binding.c returns the address of a local variable. This can lead to undefined behavior and should be addressed to ensure the code's correctness and stability.

Possible Solution
One possible solution would be to dynamically allocate memory for the relevant variable using malloc or a similar function and return the dynamically allocated memory. However, since the code is in a third-party package, modifying it directly may not be ideal.

Start with sqlite3-binding.c at sqlite3SelectNew and reproduce the warning with go build. Examine the local Select standin and pNew usage, then verify completion by rebuilding without the warning while preserving existing package behavior.
