https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D272670 Bug ID: 272670 Summary: lang/ecl: ECL crashes instead of signaling condition on stack overflow Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: olgeni@FreeBSD.org Reporter: kevinz5000@gmail.com Flags: maintainer-feedback?(olgeni@FreeBSD.org) Assignee: olgeni@FreeBSD.org Attachment #243557 text/plain mime type: Created attachment 243557 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D243557&action= =3Dedit Minimal reproduction ECL has a stack overflow detection mechanism that is supposed to signal a s= tack overflow condition to allow graceful recovery on stack overflow. This does = not appear to be working on the system I tested this on, using the ECL from lat= est packages. Steps to reproduce: 1. Get stack-overflow.lisp (attached) 2. ecl --load stack-overflow.lisp pid 23924 comm ecl has trashed its stack, killing terminated by signal SIGILL (Illegal instruction) I can't tell if this is the compiler stack canary, or the stack guard packa= ges, that is killing this process. Re-running through truss seems to suggest that it's the OS killing it: mmap(0x805b9b000,65536,PROT_READ|PROT_WRITE,MAP_PRIVATE,3,0x0) =3D 34455793= 664 (0x805b9b000) mmap(0x805bab000,65536,PROT_READ|PROT_WRITE,MAP_PRIVATE,3,0x0) =3D 34455859= 200 (0x805bab000) SIGNAL 11 (SIGSEGV) code=3DSEGV_ACCERR trapno=3D12 addr=3D0x7fffdfffe668 pid 23984 comm ecl has trashed its stack, killing _umtx_op(0x80023c080,UMTX_OP_WAIT_UINT_PRIVATE,0x0,0x0,0x0) ERR#4 'Interrup= ted system call' But I can't really tell and don't want to jump to conclusions. > uname -a FreeBSD foxtrot 13.1-RELEASE-p6 FreeBSD 13.1-RELEASE-p6 GENERIC amd64 > pkg info -f ecl ecl-21.2.1_1 Name : ecl Version : 21.2.1_1 Installed on : Wed Mar 22 20:43:51 2023 PDT Origin : lang/ecl Architecture : FreeBSD:13:amd64 Prefix : /usr/local Categories : lisp lang Licenses : LGPL20 Maintainer : olgeni@FreeBSD.org WWW : https://common-lisp.net/project/ecl/main.html Comment : ANSI Common Lisp implementation Options : ASDF : on DFFI : on SAGE : on SOCKETS : on THREADS : on X11 : off Shared Libs required: libgmp.so.10 libgc.so.1 libgc-threaded.so.1 libffi.so.8 libatomic_ops.so.1 Shared Libs provided: libecl.so.21.2 Annotations : FreeBSD_version: 1301000 --=20 You are receiving this mail because: You are the assignee for the bug.=
