SystemTap追踪user-space程序时需要安装user-space程序的debug-info包。举个例子:

 # stap -d /bin/ls --ldd -e 'probe process("ls").function("xmalloc") {print_usyms(ubacktrace())}' -c "ls /"
semantic error: while resolving probe point: identifier 'process' at <input>:1:7
        source: probe process("ls").function("xmalloc") {print_usyms(ubacktrace())}
                      ^

semantic error: no match (similar functions: malloc, calloc, realloc, close, mbrtowc)
Pass 2: analysis failed.  [man error::pass2]

安装coreutils-debuginfo包:

# zypper in coreutils-debuginfo
