alleyoop 0.9.8-1 (i386 binary) in ubuntu bionic

 Alleyoop is a GNOME front-end to the Valgrind memory checker, including
 features like intelligently suppressing errors and launching editors at
 the error position in the source code.
 .
 Valgrind helps you to find memory-management problems in your programs.
 When a program is run under Valgrind's supervision, all reads and
 writes of memory are checked, and calls to malloc/new/free/delete are
 intercepted.
