The implementation of assert in linux is as follows:
define assert(expr) (__ASSERT_VOID_CAST (0))
After defining NDEBUG in sqlite, some variables will be undefined,
and referencing variables in assert will cause compilation errors.
sqlite3.c:28729:23: error: ‘mutexIsInit’ undeclared (first use in this function)
28729 | assert( GLOBAL(int, mutexIsInit) );

According to the standard definition, assert should return a void expression
https://pubs.opengroup.org/onlinepubs/007904875/basedefs/assert.h.html
This patch involves two changes:
If you define the NDEBUG macro, assert does not use any parameters and directly returns a void expression.
assert should return a void expression and cannot use do-while statements.
If the following code , a compilation error will occur.

CURRENT_REGS may change during assert handling, so pass
in the 'regs' parameter at the entry point of _assert.

_assert is a kernel procedure, entered via system call to make the core
dump in privileged mode.
Running exit() from this context is not OK as it runs the registered
exit functions and flushes streams, which must not be done
from privileged mode as it is a security hole.
Thus, implement assert() into user space (again) and remove the exit()
call from the kernel procedure.
