I'm posting this here, but most are free to ignore it unless this bug
(ns_eval of a comment) is affecting you. This just seemed like a good
place to put the information so that Dossy has access to it.
This bug is caused by the optimization in tcl to the way eval handles
pure lists. By changing the pure list into one with a string
representation, the problem goes away. A diff from the original init.tcl
file to one that doesn't have the issue is:
(210)>> diff init.tcl /tmp/myinit.tcl
208a209
> string length $args
In context, it looks like:
proc _ns_helper_eval {args} {
set didsaveproc 0
if {[info proc _saved_ns_eval] == ""} {
rename ns_eval _saved_ns_eval
proc ns_eval {args} {
set len [llength $args]
if {$len == 0} {
return
} elseif {$len == 1} {
set args [lindex $args 0]
}
uplevel 1 $args
}
set didsaveproc 1
}
string length $args
set code [catch {uplevel 1 $args} result]
if $didsaveproc {
rename ns_eval ""
rename _saved_ns_eval ns_eval
}
return -code $code $result
}
