#3038 TclLookupSimpleVar Interp->globalNsPtr

[Anonymous]

In tclvar.c::TclLookupSimpleVar(), I am getting a crash:

Unhandled exception at 0x100a8526 (tcl84g.dll) in
PBX.exe: 0xC0000005:
Access violation reading location 0xfeeeffd6.

It looks like the cxtNsPtr has a value of 0xfeeefeee that
it gets from
<globalNsPtr>. Why would this variable have this
question? I am not using
namespaces, at least I am not knowingly doing anything
with them or messing
with them. I am using 8.4.9, Windows XP SP-2, MS
VisualC++.net (2003)

if ((cxtNsPtr->varResProc != NULL || iPtr-
>resolverPtr != NULL) &&
!(flags & LOOKUP_FOR_UPVAR))

cxtNsPtr = 0xfeeefeee, cxtNsPtr->varResProc = ????
Flags = 0x00000001
iPtr->resolverPtr is not null)

Here is the stack:

The last call of mine was to Tcl_SetVar( theTcl,
varName.c_str(),
value.c_str(), TCL_GLOBAL_ONLY ); both varName and
value are both populated
so it is getting <const char *> with actual values (not
null) and theTcl is
a result of Tcl_CreateInterp() followed by Tcl_Init().

For reference, I am calling Tcl_FindExecutable(),
Tcl_CreateInterp(), and Tcl_Init(), in that order.

Any ideas?
