[xsd-users] memory not deallocated ?

[frederic heem]

Hi boris,
lid_conf.xsd and driver.cxx has been changed, only the attribute name is 
optional. 
When program is executed under the control of valgrind, it shows that some 
memory hasn't been deallocated. I reckon this memory is allocated once for 
the whole life of the program, so it may be NOT a memory leak. However, I do 
prefer having a program which deallocate everything so that "real" memory 
leak can be detected quicker.
