Since\nthe template is actually stored in read-only memory, when the function\nexecutes the following call we get an oops:\n\n\tsnprintf(*pvs_name, sizeof(\"speedXX-pvsXX-vXX\"), \"speed%d-pvs%d-v%d\",\n\t\t speed, pvs, pvs_ver);\n\nTo fix this issue, we instead store the template name onto the stack by\nusing the following syntax:\n\n\tchar pvs_name_buffer[] = \"speedXX-pvsXX-vXX\";\n\nBecause the `pvs_name` needs to be able to be assigned to NULL, the\ntemplate buffer is stored in the pvs_name_buffer and not under the\npvs_name variable.",
