| Description: |
With 8.5.4rc0, --enable-symbols --disable-threads, -DPURIFY added. If I run the test suite under valgrind (with proc exit args {} at the end) there's a lot of noise.
It's clear to me, that this valgrind output isn't maximal
helpful. There are probably only a few spots, if ever, which may be used to write 'real' leaking scripts. Though, I can't show such a script atm. Anyway, memory hygiene of 8.5.4rc0 isn't as bright as it was in earlier versions.

Logged In: YES user_id=80530 Originator: NO time for testing RCs is past. If there's still memleaks in the 8.5.4 release, open a new ticket. dgp added on 2008-08-12 21:55:32: Logged In: YES user_id=80530 Originator: NO RC1 now available for testing. andreas_kupries added on 2008-08-12 03:42:05: Logged In: YES user_id=75003 Originator: NO Ok, a fix was committed to the 8.5 branch. Porting to 8.4 and 8.6 now. Same test triggers. Same fix works. Committed. It is unclear to me if I can close the bug now, or if there are other problems to handle, just by someone else? Lowering prio. Unassigning. msofer added on 2008-08-10 06:05:26: Logged In: YES

The script
while {1} {
catch {
proc p x {
set y [string tolower $x]
return "$x:$y"
}
procbodytest::proc t x p
} result
incr i
}
leaks a CmdFrame when sourced (but not when run from the command line), both in 8.5 and 8.6. The
stack trace is at http://paste.tclers.tk/1130, the growth can easily be seen in top.
