Bug: vsnprintf on GCC crashes with %s #10375
Description
What happened?
When compiling with Vulkan support on -DGGML_VULKAN=on and GCC, after running llama-cli I get a SIGSEGV on the ggml_log_internal_v function, in particular on the first vsnprintf line.
Searching online I found a lot of issues with vsnprintf and %s. I tried removing the statement using that log function with a %s and it works:
Name and Version
Cannot run as it crashes before printing anything useful
./build/bin/llama-cli --version
ggml_vulkan: Found 1 Vulkan devices:
fish: Job 1, './build/bin/llama-cli --version' terminated by signal SIGSEGV (Address boundary error)

Using built-in specs.
