Hoo, nasty.  Tcl_GetVar() is resetting interp->result.  Not sure why
we didn't see this before ... maybe it didn't use to?  Anyway, the
order of execution in
       ereport(ERROR,               (errmsg("%s", interp->result),                errcontext("%s\nin PL/Tcl function
\"%s\"",                          UTF_U2E(Tcl_GetVar(interp, "errorInfo",
TCL_GLOBAL_ONLY)),                          prodesc->user_proname)));
 

is machine-dependent, which explains why I didn't see it on HPPA.
