[zeromq-dev] Assertion failure in libzm msg.cpp:296 when reading from ZMQ_STREAM socket

[Auer, Jens]

Hi,

I could reproduce the issue on the master. I even was lucky and it crashed really early. The stack trace is:
#0  0x00007f8ff2c185d7 in raise () from /lib64/libc.so.6
#1  0x00007f8ff2c19cc8 in abort () from /lib64/libc.so.6

Yes, you should build libzmq master and run your application with it. If it solves your problem, all is well.

Hi,

have there been any fixes relating to this in the current master? I could check with the code from the repository.

Cheers,

Pieter,

You were probably checking the source in libzmq master repository. Line 296 is blank in the msg.cpp source file.

However, in the zeromq-4-1 repository there is definitely an assertion on that line. Since the OP said they were using 4.1.3 then that’s the correct repository to check.
