https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D215427 Bug ID: 215427 Summary: [patch] games/acm coredumps immediately on start Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Keywords: patch Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: jgibbons@protogate.com Keywords: patch Created attachment 178115 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D178115&action= =3Dedit A new file which should be added to /usr/ports/games/acm/files/ to add code= to V/lib/InitAWin.c to zero w->csPool2 after malloc()ing w. games/acm may coredump immediately after starting on systems which do not z= ero malloc()ed memory. This is because one of the fields of a malloc()ed data structure (w) contains a pointer (w->csPool2), and if that pointer is never used, then later code will find the pointer is non-NULL and try to free() t= he memory pointed to by the pointer. The attached patch adds code to set the pointer to NULL after the initial malloc() call, so later code does not try= to free() it. --=20 You are receiving this mail because: You are the assignee for the bug.=
