CGDB hangs while "Reading symbols from..."

CGDB hangs after emitting the following text in the GDB window:

I build CGDB from the latest stable source (https://github.com/downloads/cgdb/cgdb/cgdb-0.6.6.tar.gz) and it also has this problem.

David,

I am currently trying to reproduce this bug. I was wondering if you can provide some information about your version of linux and your kernel config file.

Thanks!

For me, it hangs directly after, in cgdb.c, line 1329: if (select(max + 1, &rset, NULL, NULL, NULL) == -1) { ...

[Timo Laru (timo-laru)]

Happens every time when symbols being loaded reside on NFS share.

This issue appears to be a bug in cgdb

[Kalle Raiskila (kraiskil)]

If you compile gdb from source and use that as the cgdb backend, does it repeat?
Does it hang if you start cgdb without a debuggee as command-line parameter?

I might have just reported a dupe: https://bugs.launchpad.net/ubuntu/+source/cgdb/+bug/1357378
