I'm unsure if the problem is my code or if I found a compiler bug.

The problem is your code. In GNU assembler, parentheses are used to dereference like unary * is in C, and you can only dereference a register, not memory. As such, writing 12(%0) in the assembly when %0 might be memory is wrong. It only happens to work in GCC because GCC chooses to use a register for "rm" there, while Clang chooses to use memory. You should use "r" (bytes) instead.

Also, you need to tell the compiler that your assembly is going to modify the array, either with a memory clobber or by adding *(unsigned char (*)[16])bytes as an output. Right now, it's allowed to optimize your printf to just hardcode what the values were at the beginning of the program.

Fixed code:

You can use a type predicate to define a user-defined type guard like this:

The optional identifier ? is for the last thing, either a characters or group. So the expression ([a-z0-9]{1,3})_? makes the underscore optional, but not the preceding group. The solution is to move the underscore into the parenthesis.

This is exactly the reason why coroutines were invented and how they differ from threaded concurrency. Coroutines don't block, but suspend (well, they can do both). And "suspend" isn't just another name for "block". When they suspend (e.g. by invoking join()), they effectively free the thread that runs them, so it can do something else somewhere else. And yes, it sounds like something that is technically impossible, because we are in the middle of executing the code of some function and we have to wait there, but well... welcome to coroutines :-)

You can think of it as the function is being cut into two parts: before join() and after it. First part schedules the background operation and immediately returns. When background operation finishes, it schedules the second part on the main thread. This is not how coroutines works internally (functions aren't really cut, they create continuations), but this is how you can easily imagine them working if you are familiar with executors or event loops.

delay() is also a suspending function, so it frees the thread running it and schedules execution of the code below it after a specified duration.

Here is the solution I found :

Changin xvimagesink by ximagesink :

sink = gst_element_factory_make ("xvimagesink", NULL); g_assert(sink);

becomes

sink = gst_element_factory_make ("ximagesink", NULL); g_assert(sink);

Hope it will help some of you facing the same problem.

So if the key for os.getenv() is invalid, it returns the default values that you pass as the second parameter. If you don't set this default value, it returns a None. Possible Fixes:

I had the same issue with fixed footer at bottom and its mainly due to html structure. This post has well explained fixed bottom footer

Ideally, your cleanup should look like this:

You need to use the "remember" keyword for the recomposition to happen each time, as explained here: https://foso.github.io/Jetpack-Compose-Playground/general/state/

In short, your composable would look like this:
