This gives 0xC0000005 at 0x1005E45E every time:

file://e:\ma[Tab][Home]

(I know it's malformed.) I first tried to complete a path ([Tab]). Then I wanted to go to the beginning to insert a space (still thinking of completion). I was actually trying to get to

TCC 11.00.50 Windows 7 [Version 6.1.7600]
TCC Build 50 Windows 7 Build 7600

I can't reproduce this. It just tab completes for me.

Not reproducible here. Is this with no plugins or key aliases?

Yes. I just tried it with no plugins and no aliases/functions at all
... still utterly reproducible.

You can shorten it to:
Code:
file://[Tab][Home]

The moment I press tab, a filename is completed. Pressing home moves to the
left edge.

TCC 11.00.50 Windows 7 [Version 6.1.7600]
TCC Build 50 Windows 7 Build 7600


Is there any chance that the current folder and/or contents are aiding in
the failure? If you post a dir, I can try to reproduce contents more
precisely.

When I press [Tab] nothing happens, even in the original example where
there exist completions.

It happens in any directory.

In OPTION, under "filename completion", the first three are checked;
"search path" is not.

It also happens in v10 and v10LE. It doesn't happen in v9.

I never see any completion.

|I never see any completion.

This will do it too:

Code:
mailto://[Tab][Home]
Probably unrelated and a little odd:

Code:
file://[Enter]
opens MyComputer.

My option check boxes are the same as yours. I had a folder C:\RAM\Test with
two files file1.txt and file2.txt. I keyed "file://" and then used procmon
and filtered on the PID of TCC. I pressed TAB and then stopped procmon and
saved the results as a CSV.

The results are here:

I've tried this on XP, Server 2008, and Windows 7, in 32 and 64-bit, and
I've been unable to reproduce it anywhere.

Anybody else able to reproduce this?

The stack is impossible.

Yes, I thought being 0x915E bytes into a function as small-sounding as
SetCodePage was a little odd. But that's what WinDbg said.

The first 4 are the TCC ones. I don't have a "FileCompletion"
