'true' returns nothing successfully, while false returns nothing unsuccessfully. As a result, using 'while false' would only exit your loop rather quickly, while not executing the code beneath. 'while' and 'while true' vary in what the condition is for the loop. If nothing is passed to 'while' then it assumes 'while true'.

Production C code compiled without the dash-g option is running, and seems to be in an infinite loop. Is there a way to tell? Is there a diagnostic tool that will report what objects or what lines of code or even what functions are being executed?

SYNOPSIS
cut-diff [option ...] file1 file2
DESCRIPTION
cut-diff is a diff command that uses diff feature in Cutter. It shows difference with color.
It's recommended that you use a normal diff(1) when you want to use with patch(1) or you don't need color.
OPTIONS
--version
cut-diff shows its own version and exits.
-c [yes|true|no|false|auto], --color=[yes|true|no|false|auto]
If 'yes' or 'true' is specified, cut-diff uses colorized output by escape sequence. If 'no' or 'false' is specified, cut-diff never
use colorized output. If 'auto' or the option is omitted, cut-diff uses colorized output if available.
The default is auto.
-u, --unified
cut-diff uses unified diff format.
--context-lines=LINES
Shows diff context around LINES.
All lines are shown by default. When unified diff format is used, 3 lines are shown by default.
--label=LABEL, -L=LABEL
Uses LABEL as a header label. The first--label option value is used as file1's label and the second --label option value is used
asfile2's label.
Labels are the same as file names by default.
EXIT STATUS
The exit status is 0 for success, non-0 otherwise.
TODO: 0 for non-difference, 1 for difference and non-0 for errors.
EXAMPLE
In the following example, cut-diff shows difference between file1 and file2:
% cut-diff file1 file2
In the following example, cut-diff shows difference between file1 and file2 with unified diff format:
% cut-diff -u file1 file2
