| Description: |
A panic about a missing UpdateStringProc
has been reported on AIX systems. See
http://groups.google.com/groups?hl=en&selm=fec9a0b3.0110291044.5480155c%40posting.google.com
I'm still working on understanding the
comment on line 189 of generic/tclPkg.c,
but the code there is clearly broken:
/* ...
* Detect this situation by checking that this
library has been correctly
* initialised. If it has not been then return
immediately as nothing will
* work.
*/
if (!tclEmptyStringRep) {
Tcl_AppendResult(interp, "Cannot load package
\"", name,
"\" in standalone executable: This
package is not ",
"compiled with stub support", NULL);
return NULL;
}
Since "nothing will work", the routine
Tcl_AppendResult() should not be called,
because, as promised, it will not work!
It panics when tclEmptyStrinRep is not initialized.
Similar code is in Tcl_PkgPresentEx().

I can't test though, because I don't have a test package that demonstrates the bug. Writing to Guy Mason, who originally reported the trouble on c.l.t. to see if he can test. | |||
