-In the interests of debugging SSLeay, there is an option to compile
-using some simple memory leak checking.
-
-All malloc(), free() and realloc() calls in SSLeay now go via
-Malloc(), Free() and Realloc() (except those in crypto/lhash).
-
-If CRYPTO_MDEBUG is defined, these calls are #defined to
-CRYPTO_malloc(), CRYPTO_free() and CRYPTO_realloc().
-If it is not defined, they are #defined to malloc(), free() and realloc().
-
-the CRYPTO_malloc() routines by default just call the underlying library
-functons.
-
-If CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) is called, memory leak detection is
-turned on. CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) turns it off.
-
-When turned on, each Malloc() or Realloc() call is recored along with the file
-and line number from where the call was made. (This is done using the
-lhash library which always uses normal system malloc(3) routines).
-
-void CRYPTO_mem_leaks(BIO *b);
-void CRYPTO_mem_leaks_fp(FILE *fp);
-These both print out the list of memory that has not been free()ed.
-This will probably be rather hard to read, but if you look for the 'top level'
-structure allocation, this will often give an idea as to what is not being
-free()ed. I don't expect people to use this stuff normally.
