From: Anton Prokofiev on 25 Apr 2010 17:04 Hello, All! I've found a strange behavior of ActiveState tcl 8.5.: When I start tclsh8.5 it create file in current directory with crazy name ???@???@8 And it did not remove it when I exit with "exit" command. Any Ideas what could it be?

We have had this reported from other versions of Ubuntu twice before: http://bugs.activestate.com/show_bug.cgi?id=80035 As you see there isn't a solution posted there. I'm wondering if it may be some obscure i18n/l10n bug. Do you have a standard English setup, or is it oriented towards another language as the default? Perhaps you can add your env info to that bug and we can see if there is any similarities that can be found. As the same AT 8.5 isn't doing this on other machines, I suspect we have an issue at the core level related to the init that is interacting oddly with the libc on Ubuntu under certain circumstances.

Peculiar. I don't know what kind of a file Linux ActiveTcl 8.5 would try to create when starting. My first thought was that perhaps it was something associated with the interactive history facility - but when I look in the generic/ tclhistory.c file, I don't see an open being invoked. Does it happen _immediately_ after starting tclsh8.5 ? Do you have a $HOME/.tclshrc file that might be performing some function that creates the file?

He asked me to write this idea in an AT bugreport, which I did in http://bugs.activestate.com/show_bug.cgi?id=80239 . I am not aware of a sequel :/ -Alex

We'll reexamine this and provide a fix in the next ActiveTcl. Still not sure why running libc (which has been possibly forever on Linux to get the glibc version) should leave that odd file on Ubuntu.
