[rabbitmq-discuss] [rabbitmq_c] Infinite wait in login_with_properties function

[Haster]

Hi there!

Today I have caught a bug that my program could not stop.
I used a gdb and found that application was on recv method. Call stack:

#0  0x0000003435c0dc81 in recv () from /lib64/libpthread.so.0
#1  0x00002aaaad84ead1 in ?? () from

#3  0x00002aaaad84c19e in ?? () from

#4  0x00002aaaad84c72c in amqp_simple_wait_method ()
   from
/import/home/yury.alioshinov/linux_i686/5102/lib/librabbitmq_c.so.1.1.1
#5  0x00002aaaad84cab6 in ?? () from
/import/home/yury.alioshinov/linux_i686/5102/lib/librabbitmq_c.so.1.1.1
#6  0x00002aaaad84ce8a in amqp_login_with_properties ()
   from
/import/home/yury.alioshinov/linux_i686/5102/lib/librabbitmq_c.so.1.1.1

#11 0x00000034350d40cd in clone () from /lib64/libc.so.6

So, method login_with_properties is blocked, and there is some usecase where
program execute amqp_send_header in amqp_login_inner without errors but
can't get data from amqp_simple_wait_method.

Maybe rabbitmq_c needs nonblock login method?
