Use the macro without arguments (see sfepy/fem/extmods/common.h for
definition):

check_memory_integrity();

and do not forget to rebuild the sources.

After adding it to convect_build_vtg()

...
default:
errput( ErrHead "ERR_Switch\n" );
return( RET_Fail );
}
check_memory_integrity();
return( RET_OK );
}
...

and typing "make", I get tons of

checking memory integrity in
sfepy/terms/extmods, sfepy/terms/extmods/termsNavierStokes.c,
convect_build_vtg(), 476:
allocated memory: 8 records, usage: 52032, max: 52032
memory OK.

- trying with the examples/navier_stokes/navier_stokes2d.py

Also try changing the debug flags in site_cfg.py:

debug_flags = '-DDEBUG_FMF'

or even

debug_flags = '-DDEBUG_FMF -DDEBUG_MESH'

It printed the debug results for examples/navier_stokes/navier_stokes2d.py
Then I tried running the convective_difffusive.py and it did not print any
line containing allocated memory report:
