2dcb7f74 - fix: free ctx_copy in ggml_opt_free to plug per-training-session leak (#21592)

fix: free ctx_copy in ggml_opt_free to plug per-training-session leak (#21592) * fix: free ctx_copy in ggml_opt_free to plug per-training-session leak ggml_opt_alloc populates opt_ctx->ctx_copy via a free+init pair every time the allocated graph shape changes. The last ctx_copy from the final ggml_opt_alloc call survives until ggml_opt_free is invoked, but ggml_opt_free was only freeing ctx_static and ctx_cpu, never ctx_copy. Each opt_ctx lifetime therefore leaks the final per-batch context — ~900 KB for a typical GNN training session in sindarin-pkg-tensor, surfaced via AddressSanitizer. ctx_copy is nullptr-initialized and ggml_free() handles NULL safely, so the new release is guard-free. * Update ggml/src/ggml-opt.cpp Co-authored-by: Johannes Gäßler <johannesg@5d6.de> --------- Co-authored-by: realorko <realorko@nowhere.com> Co-authored-by: Johannes Gäßler <johannesg@5d6.de>
