Could it be possible to add an option like --heap-up-fill --heap-down-fill (like for stack with malloc), that fills heap memory with a specified values (when entering a function and leave a function)?

The value zero is the worst possible value to use for such initialization, from the viewpoint of quickly producing better software by discovering and identifying bugs sooner. Using the value zero tends to hide many bugs. A much better value is 0x8181...81. This value is non-zero, odd, negative as a signed integer, a very unlikely floating-point value, very often not a valid pointer value, and instantly recognizable in any dump of memory. It was used to great success as the "core constant" (the value of uninitialized RAM) by the Michigan Terminal System for IBM 360/67 and successors, from the early 1970s (50 years ago!) until the demise of MTS around 2000. _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
