It works fine for: stap -vve 'probe kernel.function("sys_open"){}' -c ls stap -vve 'probe process("./test").syscall {}' -c ls only got crashed when stap -vve 'probe process.syscall {}' -c ls I guess the reason is the spawn process by stap is being hitted. Some signals are delayed/messed so that BUG_ON in utrace_get_signal is triggered. -- http://sourceware.org/bugzilla/show_bug.cgi?id=6964 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
