<pre>This clashes with the documentation for this interface but not it's general
usage so it's gone unnoticed. <a href="https://pastebin.com/tTmzeeid">https://pastebin.com/tTmzeeid</a>
uint32_t gpu_count = 1;
/* TODO: This just selects first GPU. */
vkEnumeratePhysicalDevices (instance, &gpu_count, &gpu);
Changing this to...
uint32_t gpu_count = 0;
vkEnumeratePhysicalDevices (instance, &gpu_count, NULL);
gpu_count = 1;
/* TODO: This just selects first GPU. */
vkEnumeratePhysicalDevices (instance, &gpu_count, &gpu);
works around the issue.</pre>
