I believe TEST TWO END might also have go through fine. The message just
wasn't printed out. Segfault does it -- it eats up some of the messages in
the out stream buffer. You can get all the outputs in gdb though.
>From the stack you provided yesterday, the segfault signal happened when the
Workplace info is received by the client.It's the second message received
from the server when you login. When I ran gdb, I created a breakpoint at
*
b AsioClient.cpp:176*
and then looked at the value in current
*p current *
after the statement
char* current = m_input_buffer;
The first one, "LS\n", was fine. The second one, "WL \n", I felt may be
carrying junk characters. So tried to set it zero.
Thanks
