--------------------------------------------------------------------

To fix this I am pulling in an autoconf module to enable/disable debug and 
modified it a little.
https://www.gnu.org/software/autoconf-archive/ax_check_enable_debug.html

The syntax will be as follows:

||{{./configure --enable-debug=}}||Compiler Options Used||Default?||NDEBUG||
|{{yes}}|{{-g -O0}}| | |
|{{info}}|{{-g -O2}}|yes|#defined|
|{{profile}}|{{-g -O0 -pg}}| |#defined|
|{{no}}|{{-O2}}| |#defined|

{noformat}
$ ./configure | grep debugging
checking whether to enable debugging... no just optimize
$ ./configure --enable-debug=yes | grep debugging
checking whether to enable debugging... yes without any optimization
$ ./configure --enable-debug=no | grep debugging
checking whether to enable debugging... no just optimize
{noformat}

>                 URL: https://issues.apache.org/jira/browse/THRIFT-4163
>             Project: Thrift
>          Issue Type: Bug
>          Components: Build Process
>    Affects Versions: 0.10.0
>            Reporter: James E. King, III
>            Assignee: James E. King, III
>            Priority: Critical
>
> In a project that uses thrift I was looking at a core and found an assertion 
> inside thrift triggered it.  This was rather strange being in a release build 
> of thrift.
> To understand if assertions are active in release builds, I modified 
> PlatformSocket.h and added this close to the top:
> {noformat}
> #ifdef NDEBUG
> #error "NDEBUG IS SET: ASSERTIONS ARE IGNORED"
> #else
> #error "NDEBUG IS NOT SET: ASSERTIONS ARE ACTIVE"
> #endif
> {noformat}
> Then I built the ubuntu dockerfile and started a debian package distribution 
> build:
> {noformat}
> # docker build -t thrift build/docker/ubuntu
> # docker run -v $(pwd):/thrift/src -it thrift /bin/bash
> # dpkg-buildpackage -d -tc 2>&1 | grep NDEBUG
> ./src/thrift/transport/PlatformSocket.h:25:2: error: #error "NDEBUG IS NOT 
> SET: ASSERTIONS ARE ACTIVE"
>  #error "NDEBUG IS NOT SET: ASSERTIONS ARE ACTIVE"
> {noformat}
> Assertions should not be active in release builds.
> Assertions really shouldn't be used; exceptions are much better for C++.  
> That's covered in THRIFT-3978 however.  To fix this issue, the autoconf 
> system needs to set NDEBUG for release builds.
> I checked the cmake build environment and it does not suffer from this issue.
