[TCLCORE] Something is very wrong in Tcl_InitHashTable.

[Mo D. <md...@cy...>]

There seems to be a core dumping bug in Tcl_InitHashTable that
it only appears in 8.4. I can run the exact same code
in Tcl 8.3 with no problems.

Here is the bit that crashes:

static Tcl_HashTable driverTable;

int TkGSInitDriverTable() {
  Tcl_InitHashTable(&driverTable, TCL_STRING_KEYS);
}

This is from the tkgs module, you can check it out
of the Net CVS using the module name "tkgs".


GDB prints a backtrace like this from the crash:

#0  0x401ab967 in TclDatedef () from 
/usr/local/project/install/Tcl/lib/libtcl8.4g.so
#1  0x403a1e1b in TkGSInitDriverTable () at 
/home/mo/project/tkgs/src/generic/tkgsDriver.c:14


I think this was caused by Paul's recent Hashtable
changes.
