#36 case in CSndUList::remove_

[mingyiliu]

I use udt library on arm . but i modify the keepalive time in 8s , reduced the thread stack size to 128k . while , udt become fragility ,and i don't know how to handle such issue.
crash :

0 CSndUList::remove_ () from /usr/local/lib/libudt.so

1 CSndUList::pop () from /usr/local/lib/libudt.so

2 CSndQueue::worker () from /usr/local/lib/libudt.so

3 ?? () from /lib/libpthread.so.0

Thank you for your attention .

Hi.
We have exactly the same call stack in our crash dump.
udt is compiled for Windows x64.
Recently we had several application crashes with Access Violation.

udt!CSndUList::remove_+0x13
udt!CSndUList::pop+0x89
udt!CSndQueue::worker+0xb5

Could not find repro steps or conditions for this crash to reproduce.

Thank you,
