DYI GL object leak checker.
static void check_for_leaks()
{
GLuint max_id = 10000; // better idea would be to keep track of assigned names.
GLuint id;
// if brute force doesn't work, you're not applying it hard enough
for ( id = 1 ; id <= max_id ; id++ )
{
#define CHECK( type ) if ( glIs##type( id ) ) fprintf( stderr, "GLX: leaked " #type " handle 0x%x\n", (unsigned int) id )
CHECK( Texture );

Examples of subtly incorrect GLSL ES 3.1 snippets
// Implicit conversion in ndx = 0 assignment, should be ndx = 0u
for (uint ndx = 0; ndx < count; ndx+++)
...
// Implicit conversion in ndx+2, should be ndx+2u
uint ndx = ...;
myArray[ndx+2] = value;
// Implicit conversion, array.length() returns int
uint threadCount = ...;

C/C++ tips for using printf-style functions
// C/C++ tips for using printf-style functions
// Lots of manipulation can be expressed simply and fast with printf-style formatting
// Also helps reducing the number of temporaries, memory allocations or copies
// ( If you are looking for a simple C++ string class that is printf-friendly and not heap-abusive,
// I've been using this one: https://github.com/ocornut/Str )
