The ROCm HIP runtime (libamdhip64) reads the TEMP environment variable as its JIT kernel-cache temp directory. Commitdb3eb01added TEMP=1.0 to the env files as a sampling default; the serve scripts export it via set -a. HIP then used the path "1.0" for its cache, failed, and segfaulted with a NULL-refcount unref (offset 0x446153 in libamdhip64) during model tensor upload (ggml_backend_cuda_buffer_set_tensor). This crashed frank-default- large on every restart from Aug 13 16:22 onward; the earlierc984a3e"fix" (KV/batch changes) was unrelated. Rename the sampling variable TEMP -> TEMPERATURE in both env files and serve scripts. llama-server still receives --temp from the renamed var, so sampling defaults are unchanged. The HIP runtime no longer sees a bogus TEMP value. Affects frank-default-large (dankclaw) and frank-default-small (dankserver).
