So it works the opposite way around to what you might expect. wxMaxima
is the server and maxima is the client.
Looks like wxMaxima uses a wx routine to start a server but encounters
an exception:
Breakpoint 1, wxMaxima::InitSession (this=0x87f082e1800) at wxMaxima.cpp:244
244 int defaultPort = 4010;
(gdb) r
The program being debugged has been started already.
Start it from the beginning? (y or n) n
Program not restarted.
(gdb) n
246 wxConfig::Get()->Read(wxT("defaultPort"), &defaultPort);
(gdb)
247 m_port = defaultPort;
(gdb)
249 while (!(server = StartServer()))
(gdb) s
wxMaxima::StartServer (this=0x87f082e1800) at wxMaxima.cpp:644
644 bool wxMaxima::StartServer()
(gdb) n
646 SetStatusText(wxString::Format(_("Starting server on port %d"),
m_port), 1);
(gdb)
648 wxIPV4address addr;
(gdb) n
651 addr.LocalHost();
(gdb)
656 addr.Service(m_port);
(gdb)
658 m_server = new wxSocketServer(addr);
(gdb) s
operator new (sz=200)
at
/usr/src/gnu/lib/libstdc++-v3/../../gcc/libstdc++-v3/libsupc++/new_op.cc:50
50 operator new (std::size_t sz) throw (std::bad_alloc)
That is with a wxwidgets built with symbols. That is all you get...
So, that could be a wx bug? Anyone with C++ skills wants to comment?
When I found this bug with the in-tree wxMaxima, I tried the newest
version too. This crashes the same. diff below:
