For the initialization of static variables within functions, based on comparison with assembly output and analysis, I believe that a call to __cxa_atexit should be included, otherwise the class object cannot be destructured on program exit.

The following references are used in the analysis process.

This function call is missing.

mov     edx, OFFSET FLAT:__dso_handle
mov     esi, OFFSET FLAT:_ZZ11get_examplevE4temp
mov     edi, OFFSET FLAT:_ZN14example_structD1Ev
call    __cxa_atexit
