i have a local function x that returns a positive integer or -1. when it returns -1, assignment $var(tmp) = function_x("$rd"); produces to syslog an error: Feb 19 07:32:44 sip /usr/sbin/sip-proxy[27284]: ERROR: <core> [lvalue.c:411]: assignment failed at pos: (1415,40-1415,40) i have had that function for years, but have not noticed these errors in earlier versions than 3.1. any ideas why the error is produced and how to get rid of it? -- juha
