https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260303 Dimitry Andric <dim@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dim@FreeBSD.org --- Comment #1 from Dimitry Andric <dim@FreeBSD.org> --- See also bug 253208, and commit https://cgit.freebsd.org/src/commit/?id=3D889b56c8cd84c9a9f2d9e3b019c154d6f= 14d9021 . The problem appears to be the setrlimit() call in SDCCmain.c: /*-------------------------------------------------------------*/ /* setStackSize - set the stack size of a running sdcc process */ /*-------------------------------------------------------------*/ static void=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20 =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 setStackSize (void) { #if defined (HAVE_SETRLIMIT) && defined (RLIMIT_STACK) struct rlimit rl =3D {4 * 1024 * 1024, 4 * 1024 * 1024}; setrlimit (RLIMIT_STACK, &rl); #endif } It segfaults immediately upon return from the setrlimit() syscall wrapper. Doing: elfctl -e +noaslrstkgap ${WRKSRC}/bin/sdcc makes the problem go away. --=20 You are receiving this mail because: You are the assignee for the bug.=
