The only checking done in this patch is to check that the format string is a valid null-terminated string; this patch doesn't attempt to check the content of the format string. gcc/analyzer/ChangeLog: PR analyzer/105899 * call-details.cc (call_details::call_details): New ctor. * call-details.h (call_details::call_details): New ctor decl.
