            Bug ID: 27984
           Summary: stap skipping partially-inlined instance, but it is
                    not inline function actually
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: zhuizhuhaomeng at gmail dot com
  Target Milestone: ---

Created attachment 13495
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13495&action=edit
the object file of libssl.so

The stap script:

probe
process("/usr/local/openresty/openssl/lib/libssl.so.1.1").function("tls_process_client_hello")
{
    var_pid = pid();
    printf("%ld\n", var_pid);
}


The build steps:
time /usr/bin/stap --sysroot=/tmp/stap-job1/sysroot -vvvvv \
        -p2 \
        -d "/usr/local/openresty/openssl/lib/libssl.so.1.1" --disable-cache \
        "test.stp"

how to reproduce it:
download the attachment, and decompress to /tmp director.
enter into the /tmp/stap-job1 direcotry and run sh make.sh.
