I am working on a problem involving the SSLeay call to PEM_read.
Unfortunately, the problem is in an inlined function and I find
that most of my tools get a little twitchy working on inline
functions. However, when the function is not inlined, the problem
goes away.
Near the end of the function, it calls another function and with
dtrace I find that one of the input parameters is garbage. However
the only place in the source that this variable is touched is earlier
when it is passed to the PEM_read function which should be setting it.
So, my goal is to either verify that PEM_read is setting this variable
or prove that it is not.
Here is the prototype of PEM_read:
int PEM_read(fp, name, header, data, len)
FILE *fp;
char **name, **header;
unsigned char **data;
long *len;
The variable I am concerned about is data. I want to capture
the address of data on the entry to PEM_read and display the
address it contains on exit and at least the beginning of the
data that points to as well. I can then double check of it is
the same as the data that is going into the other function later.
My problem is that the double redirection and need for copyin is
throwing me. I can't seem to get it right. Can sombody give me
a hand? Thanks.
