Subject: [PATCH] Defer sound system initialization until main()
|
|
|
|
The original VVVVVV source code initializes the sound subsystem
|
|
during global variable initialization. Technically speaking, the
|
|
order of initialization of global variables is unspecified. This
|
|
results in SerenityOS's dynamic linker to call Mix_OpenAudio()
|
|
(which uses EventLoop under the hood) before all global variable
|
|
initializers finish executing, resulting in an inconsistent state
|
|
that causes assertion failure.
|
|
|
|
This patch moves initialization of the culprit sound system to
|
|
a separate method, which is called first thing inside main(), thus
|
|
preventing the setup from happening during musicclass's initialization
|
|
in the global scope, which causes the aforementioned crash.
