tk_OpenFile crashes when I select file from Windows 7 virtual folders called "Libraries". sometime it display error message saying: "alloc: "invalid block: 0812C188: ef ef 0". ", sometime crashed silenly.
It reproduces both with latest ActiveTcl 8.5.9 distribution and with self-compiled tcl/tk 8.5.9.
I have the same problem under Window XP, ActiveTcl 8.5.9 base-tk8.5-thread-win32-ix86.exe.
The Tcl panic is from tclThreadAlloc.c.
Panic is when freeing ofnData.dynFileBuffer, in tkWinDialog.c, line 957.
I believe the issue is fixed (cannot be reproduced with ActiveState 8.5.9.1 build), so the bug can be closed, I think.
