[Bug general/4788] New: Exe.get() Exceptions are not being thrown

["pmuldoon at redhat dot com" <sourceware-bugzilla@sourceware.org>]

Inside

frysk/frysk-imports/frysk/sys/proc/cni/Exe.cxx

There is a test like:

if (len < 0 || len >= FILENAME_MAX)
    throwErrno (errno, "readlink");

In some situations in the field, getExe() produces garbage. However the above
exception never "surfaces" to the user level, and no indications of an error
happening has occured. If you add in a print statement something like:

if (len < 0 || len >= FILENAME_MAX)
{
    printf("readlink failed on link %s\n",link);
    throwErrno (errno, "readlink");
}

The printf is shown, but no stack trace for the exceptions. This leaves getExe()
always appearing to be correct.
