https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290958 Bug ID: 290958 Summary: ctfmerge: random Segmentation fault: 11 for `make buildkernel' on macOS Product: Base System Version: 14.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: misc Assignee: bugs@FreeBSD.org Reporter: wosch@FreeBSD.org I'm running `make buildkernel' on macOS (cross compiling) and sometimes ctfmerge crashes with a Segmentation fault: 11. The errors are random, and not for the same call. libsystem_pthread.dylib Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x00004bbc62118008 Exception Codes: 0x0000000000000001, 0x00004bbc62118008 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 This seems to be a problem with the macOS pthread library, or the use of the lib. It happens on arm and intel, and the latest macOS 26. I run `make cleankernel; make buildkernel' in a loop 100 times (ca. 2hours) and usually in 3-5 cases ctfmerge will crash. Example: for i in $(seq 1 100); do printf "."; env logrotate_max=100 debug=0 build_targets='cleankernel;buildkernel' cross-build-macos.sh >/dev/null 2>&1 || echo " i=$i exit=$?";done .......... i=10 exit=2 . i=11 exit=2 .............................................. i=57 exit=2 ....... i=64 exit=2 ............................ i=92 exit=2 ........ sh: line 2: 64617 Segmentation fault: 11 ctfmerge -L VERSION -g -o ipl.kld mlfk_ipl.o ip_nat.o ip_frag.o ip_state.o ip_proxy.o ip_auth.o ip_log.o ip_fil_freebsd.o fil.o ip_lookup.o ip_pool.o ip_htable.o ip_sync.o ip_nat6.o ip_rules.o ip_scan.o ip_dstlist.o radix_ipf.o *** [ipl.kld] Error code 139 zegrep -l 'Segmentation fault' macos.buildkernel*gz macos.buildkernel.35.gz macos.buildkernel.42.gz macos.buildkernel.7.gz macos.buildkernel.88.gz macos.buildkernel.89.gz -- You are receiving this mail because: You are the assignee for the bug.home | help
