Package: llama.cpp
Version: 8064+dfsg-2
Severity: normal
X-Debbugs-Cc: [email protected]
Dear Maintainer,
I am trying to use a Qwen3-coder model with llama.cpp and opencode. However, I
see frequent crashes of llama-server. One example can be found below. I suspect
that this is upstream llama.cpp bug #19304 (https://github.com/ggml-
org/llama.cpp/issues/19304), which was fixed about a week after the release of
the currently packaged version, though the bug reports there used different
Qwen-Coder variants.
