Here is the line in the source, ./common/tree.c - it is evaluating an
expression and the 45 is the "operation". Looking in includes/tree.c,
operator 46 is expr_funcall (whatever that means)
int write_expression (file, expr, col, indent, firstp)
...
switch (expr -> op) {
...
default:
log_fatal ("invalid expression type in print_expression: %d",
expr -> op);
}
return col;
}
I have a pretty early copy of the 4.1.1 source, but when I compare with
4.3.2 source there is a case expr_funcall in that switch statement now. Is
it possible you used a late version that has written something the older
version can now no longer parse? Is it possible to upgrade to the newest
release you can (ie later 4.1.1 or perhaps compile your own latest
version?
My guess is that it has written something to the leases file, and now
can't evaluate it properly. So that's where I'd look.
