I have latest verison of port quagga, I looks as bug in quagga,
but I dont know. Do you have any idea for solution?
It is a bug in quagga, or rather a condition that triggers a built-in
verification macro called assert(3). Normal behavior for this macro is
to terminate the program if the asserted condition fails, as it does here.
It looks if a function that calculates the length of a string gets a
larger value than it can cope with. It is possible that an internal
buffer for a string isn't large enough. In this day and age I would
respectfully call that bad coding.
You should report it to the author(s), sinze they put in this check.
It is possible to disable this bahaviour at compile time, see
assert(3). But this is unwise unless you know what you're doing.
Without diving into the source code, it is impossible to be certain that
this is not a FreeBSD bug. But it looks more like ungracefull handling
of an error condition.
