Crash in NTPPacket.swift

[jarlabanke]

I am getting crash reports from NTPPacket, not a lot since there are thousand of users, but 10 in the last two weeks. Sometimes the user has been running the app for an hour without problems. It is also weird that the log points to line 20, which is empty (but that could be an error in the reporting).

Can you send the full crash report? Can't do much with that one :) and maybe try the new master - we merged one long standing memory management issue

[Reflejo]

Have you tried the new master at that point? Do you still see this issue? I'll re-open if you do

[shuangwei-Ye]

I am getting crash reports from NTPPacket, not a lot since there are thousand of users, but 10 in the last two weeks. Sometimes the user has been running the app for an hour without problems. It is also weird that the log points to line 20, which is empty (but that could be an error in the reporting).

Do you still see this issue? i have this issue

[jarlabanke]

I still have this issue (with the latest master).
I get a
"Expected typeID 46 (CFRunLoopSource) does not match actual typeID 61 (CFSocket)"
from line 23 in NTPPacket.swift
I can post the full stack trace if someone is interested.
