Crash: GGML_ASSERT (!sched->is_alloc) followed by SIGABRT after repeated TTS requests on Intel SYCL backend.

[ciberbob-zotax]

summary, after several successful TTS requests, the qwentts.cpp backend crashes with GGML underscore ASSERT exclamation sched-, greater than-, is underscore alloc, followed by SIGABRT. LocalAI logs backend process exited unexpectedly, exit code2. Before that, clients get EOF, then connection refused, until restart. Issue 19 seems different. My backend aborts.

Thanks for the logs. Already fixed here: your log shows the embedded revision is d17c33d (2026-07-12), and the fix landed the same day in 19bbf94 "pipeline-codec: reset sched before encode alloc". Nothing SYCL specific. The pin lives in the LocalAI backend build, so a bump there is what you need.
