+The generated code uses smem.[ch] out of one of my BSD licensed projects.
+Out of smem.h :

+
+ Functions to replace  malloc()  and  free() in order to get more control
+ over memory leaks or spurious errors caused by faulty usage of malloc()
+ and free(). 
+
+
+ Sourcecode provisions:
+ 
+ Use only the following macros for memory management:
+    TSOB_FELD(type,count)  creates an array of items of given type 
+    Smem_malloC()          analogue of malloc()
+    Smem_freE()            analogue of free()
+ One may #define malloc Smem_malloC resp. #define free Smem_freE 
+ but better would be to review (and often to streamline) the sourcecode
+ in respect to those two functions. 
+
+
+ Speed versus control:
+
+ In production versions, where maximum speed is required, one may undefine
+ the macro  Smem_own_functionS  in  smem.h . 
+ This causes the above macros to directly invoke malloc() and free() without
+ any speed reduction (and without any additional use).
+ Undefinitio can be done globaly by modifying smem.h or locally by defining
+  Smem_no_own_functionS  before including smem.h .
+
+ If Smem_own_functionS remains defined, then the functions
+   Smem_malloc() 
+   Smem_free()
+ are used rather than malloc() and free().
+ They count the number of calls to maintain a rough overview of memory usage.
+ Smem_malloc() additionally checks for 0 size and Smem_free() checks for
+ NULL pointers, which they both report to stderr. Eventually one should set
+ a breakpoint in function Smem_protest() to learn about the origin of such
+ messages.
+ A status line may be obtained by  Smem_report()  or printed by Smem_stderr().
+
+ As long as the variable Smem_record_itemS is set to 0, there is not very much
+ overhead compared with malloc() and free().
+ If the variable is set to 1 by Smem_set_record_items() then all malloc()
+ results are kept in a list where they will be deleted by their corresponding
+ Smem_free() calls. If a pointer is to be freed, which is not recorded in the
+ list then an error message will be printed to stderr. The memory will not
+ be freed !
+ This mode not only may be very slow, it also consumes at least 16 byte per
+ piece of data which was obtained by malloc as long as it has not been freed.
+ Due to the current nature of the list, large numbers of memory items are freed
+ much faster in the reverse order of their creation. If there is a list of
+ 100000 strings to delete, it is very rewarding to free the youngest ones first.
+ A shortcut via hashing is available but consumes 24 bytes rather than 16.
+ (see above  Smem_with_hasH  )
+
+ The function Smem_is_recorded() can be used to check wether a pointer is
+ valid according to the list. It returns :
+   0 = is not in list , 1 = is in list , 2 = recording is off 
+
+ If one decides to start recording malloc() results in the midst of a program
+ run, one has to be aware of false protests of Smem_free() if a memory piece
+ has been allocated before recording started. This will also cause those pieces
+ to be memory leaks because Smem_free() refuses to delete them. (Freeing memory
+ that was not obtained by malloc or was already freed previously can result in
+ deferred SIGSEGV or similar trouble, depending on OS and library.)
+ Also in that case one should stop recording before ending the program, to
+ avoid a lot of false complaints about longliving memory objects.
