Enumerate the steps to reproduce the bug Compiled a cpp file that included the jsoncons files

What compiler, architecture, and operating system?

• Compiler: g++ (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44)
• Architecture: x86_64
• Operating system: CentOS Linux release 7.9.2009 (Core)

What jsoncons library version?

• [ ] Latest release 0.174.0
• [X] Other release 0.173.4
• [ ] master

[danielaparker]

I'll have a look, but we may have to drop support for g++ 4.8, it was never fully C++ 11 compliant, required many work arounds, and we no longer have test coverage for it.

[andysCaplin]

We got around this by enabling devtoolset-9, so I'm closing it.
