--- Comment #5 from Robin Whittle <rw at firstpr dot com.au> ---
I stepped through most of my test case steps with gdb 7.10-1.1 (installed as a
binary package on Debian 9 testing) on the test program compiled with gcc
5.3.1.  It is my impression that the behavior is the same, and so this bug
remains unfixed.

However, two recent versions of Codelite now drive gdb differently, and no
problems seem to occur.  I tried the above version with Codelite 9.1, and under
Windows I tried a binary download of Codelite 9.1.6 (weekly build) with TDM GCC
5.1.0-2, which installs gdb 7.9.1.  In both cases, there was no problem opening
the vector of vectors and seeing all the integers in all the second-level
vectors.

My only practical concern with this apparent bug is that it stopped me using
Codelite as I wanted, but Codelite now seems to cope fine.  In another program
I was able to look into a vector of structs each containing a string and a
deque of ints - so all is well.  

Thanks for GDB!
