[8.51a] TC hangs on WM_COPYDATA with some CD command

[MVV]

TC hangs when processing WM_COPYDATA with command cd |*.
Raw buffer data:

Code: Select all

ef bb bf 7c 2a 0d 00

I've checked it with TC 7.56a and TC 8.51a (clean configuration), both hang.

Quick command to reproduce:

Code: Select all

TCFS2 /ef "tcd(`|*`)"

This sounds lika a constructed problem, since you can't pass a path like
|*.
to TC via command line - the pipe symbol is intercepted by cmd.exe or Windows ShellExecute. Even writing `|*` doesn't work here on the TC command line. I tried
c:\totalcmd\TOTALCMD.exe /O `|*`

I agree that problem is a bit constructed but it is interesting why such a simple thing causes a hang, perhaps something is wrong in the message handler.

BTW quoted pipe is not interpreted as a pipe sign. When I start c:\totalcmd\TOTALCMD.exe /N "|*", I see a pipe in process' command line.

Hmm, even with quotes it opens a cmd.exe here. And no hangs. The only way I could get the hang was via TCFS2. I will try to find the reason.

TC 8.52b1 doesn't hang anymore in case of such command!

Thanks!
