           Summary: The caller-callee view from the "gprofng display text"
                    tool changes alignment
           Product: binutils

The attachment contains a directory that shows the problem

The caller-callee view from "gprofng display text" changes the alignment for
the last two columns half way the output and shifts the numbers to the right by
one position.

I attach two experiment directories and a run.sh script that shows the problem.
Sample output is also included in file run.res.

Both experiment directories are needed to reproduce the problem.

In file run.res, you can see the change. In the fragment below, I show the
output for 4 functions. Note the change under "Attr. IPC" for the 3-rd function
drand48. As the 4-th block shows, this shift persists from there on.
