I have traced the error to the vfprintf in dsdt_line() inside acpi.c, howev= er I have not been able to use gdb from ports or lldb to debug this effectively = due to various freezes that I've experienced (not gaining control back in the debugger or failing to execute the child in lldb's case). Adding a number of printfs, namely printf("%s\n", bf->f_name); when creating the temporary files removes the bug, but so does adding printfs when the VM shuts down which leads me to believe that this is in fact a code segment corruption rather than a race. --=20 You are receiving this mail because: You are the assignee for the bug.=
