To build:

    make all

NOTE: we FORCE disable the optimiser due to a funny problem with different compilers and systems. See below and compilers.html for details.

There is an alternate version. The reason is a funny problem: in modern systems, depending on the platform, compiler and the optimiser, it would work with one compiler with the optimiser but it would not work with the other; and if the optimiser state is changed the previous problematic compiler might work but the other one would not. We describe this in more detail in compilers.html and we encourage you to read it for entertainment if nothing else.

To use:

    ./marshall

Alternate code:

Due to the different conflicting problems with gcc and clang, we instead offer the problematic code as an alternate version whereas marshall.c has both the infinite loop and the complicated arg to _exit() commented out, changing the value passed into _exit() to 1.

Alternate build:

To see if your compiler has the problems noted:

    make alt

Alternate use:

    ./marshall.alt

Does it work in your system? That is does it not segfault, does it print it only once and does it not enter an infinite loop? Or more generally does it print the text exactly once and then exit?

Judges’ remarks:

This program prints the name of the picture. The layout is somewhat pretty though it is not the usual sort of output one would expect from printing a program!

This program was selected for the 1987 t-shirt collection.
