Xcode 6.1 quickly shutdown when activating breakpoint anywhere

[toolbits]

I use cpp-netlib 0.11.1RC2 on Xcode 6.1 + Yosemite + boost 1.56.0.
When I use boost::network::uri::uri class and make it's instance, I cannot use Xcode's debugger with breakpoints.
If there is no breakpoints and breakpoints are deactivated, that code run smoothly.
If a breakpoint is installed anywhere, Xcode's debugger quickly hung-up.

I found where is the problem.
Below code is in boost/network/uri/uri.ipp file:

if 0

                    // original code
                    ipv6address %= qi::raw

When I use original code, Xcode hung up. If fixed version is used, Xcode runs well.

Here is a sample test code https://github.com/toolbits/cpp-netlib_xcode610_test

[deanberris]

@glynos Do you have time to look at this?

[glynos]

I'll take a look when I find time this weekend. @toolbits could you check if the issue exists in the URI repo as well (https://github.com/cpp-netlib/uri)?

[toolbits]

@glynos, @deanberris thank you for your reply. I'll check new URI repo in a few days. Please wait a result.

[toolbits]

Hello @glynos, I had tested new URI class (https://github.com/cpp-netlib/uri). The result is fail. I uploaded test source codes at https://github.com/toolbits/cpp-netlib_xcode610_test2.

When I added new URI class's source codes to simple hello world project and build-debug-run, Xcode 6.1 goes to hungup.
It is strange acting. The bug occurs only when URI code was linked.
I think there are two bad codes at detail/uri_parse.cpp and detail/uri_parse_authority.cpp
Maybe the parsing code of IPv6 is too long. Xcode generates bad code or linker makes some strange symbol, etc...I don't know.

My development environment is:
o MacOSX 10.10.1
o Xcode 6.1
o Apple LLVM 6.0
o clang
o libc++ and C++11
o boost 1.56.0 (compiled with libc++ and C++11)

My boost library is uploaded at https://github.com/toolbits/boost_1_56_0_xcode610_universal_binary.
If you want to use same boost lib, please get it.
Thank you :)

We have same issue with Xcode 6.1.1 and 6.2, boost 1.57, latest cpp-netlib/uri (55ec3cd78918c42dfb874e01c9745b4daf51091b)

[Falven]

Having the same issue with Xcode Version 6.2 (6C131e), boost 1.57 and
https://storage.googleapis.com/cpp-netlib-downloads/0.11.1/cpp-netlib-0.11.1-final.tar.bz2
(213ba700e534596b44409cd6d5738b959fe41746)

Can't debug my project which uses the library extensively. Been a while since this issue was updated. Anything new?

[deanberris]

I don't know about @glynos' availability -- so it looks like this is could be fixed with changing the way we define the grammar. @toolbits do you have time to send a pull request? I'd love to review that and merge it to both the URI library and 0.11-devel. I suspect there's some things we can do to optimize our usage of Spirit here, and that we haven't been doing the "best practices" when it comes to complicated grammars.

[toolbits]

Hi, I made a pull request for this issue. I don't know about boost qi so much. Please review carefully about my modification.

[deanberris]

I think the latest in 0.11-devel should have fixed this. Can you see whether that's true @toolbits? Closing for now, assuming the parser break-up would have dealt with this already.
