You can always intercept the system calls, debugging symbols or not.
Try running a stripped executable under strace and see for yourself.

Designing C data structures is what I do, day in and day out.
What is "soft skills" the politically-correct term for?
And what would be considered "hard skills" then?

I got confused about which platforms are behaving one way or the other.
Your messages weren't very clear about it. In any case, the point is
that if it works, the implementation is adding .cat automatically.
I don't know. Maybe there was an earlier version of catopen() that

That argument just isn't valid. In as much as there can be bugs at any
level, including at the kernel and hardware level, you can't argue that any
possible security system can be logically reduced to no security just
because there are a series of steps you can take to break every link in the
chain.

POSIX doesn't define when signals are delivered. I don't recall that the
order is specified either (although most kernels will use a find-first-set-bit
instruction to find the next signal to deliver, implying that lower signal numbers
will be delivered ahead of higher signal numbers).
Synchronously generated signals (such as SIGSEGV, SIGBUS, SIGFPE) will always be

Here's something I cobbled together quickly (so no guarantees that
it works correctly;-) for Perl

use strict;
use warnings;
my $suffix = "b_";
my $buf;
$buf .= $_ while <>;
$buf =~ s/\b(subroutine|call)(\s+)(\w+ )(?=\s*\()/$1$2$suffix$3/gi;
print $buf;

Find an editor that handles refactoring for you.
Use a perl script :
something like this onliner :
perl -p -i -e 's/oldstring/newstring/g' `grep -ril oldstring *`
Make sure to backup your files before trying something like this!
