Create C executable 2.

In particular, if Valgrind aborted or crashed after identifying problems in your program, there's a good chance that fixing those problems will prevent Valgrind aborting or crashing, especially if it happened in m_mallocfree.c. If that doesn't help, please report this bug to: www.valgrind.org In the bug report, send all the above text, the valgrind version, and what OS and version you are using. Thanks. EXPECTED RESULT For valgrind to run as expected SOFTWARE/OS VERSIONS Windows: 10 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION The c program compiled just has a printf statement in it. sudo apt-get install valgrind gives: "valgrind is already the newest version (1:3.15.0-1ubuntu9.1)." -- You are receiving this mail because: You are watching all bug changes.
