With a Tcl compiled with <code>--enable-symbols</code> , the script <code><verbatim> package require Thread set t1 [thread::create] thread::send -async $t1 {lindex {}} [expr 0] </verbatim></code> results in: <code><verbatim> alloc: invalid block </verbatim></code> This happens because <code>threadSendFree</code> [https://core.tcl.tk/thread/artifact?udc=1&ln=992&name=27b80f574a4ced5a| obtains the length] of a <code>Tcl_Obj</code> before the string representation for that object is generated, and a few lines later [https://core.tcl.tk/thread/artifact?udc=1&ln=1014&name=27b80f574a4ced5a|the string representation is generated]. - foundin changed to: "trunk1"
