Same compile command on each? Any optimizations? Can you add code to print out the actual value of the pointer right after allocation and right before freeing it?

Or you can valgrind it.

And what exact version(s) of GCC, Linux, etc. are you using? Along with the two architectures.

NAME
klcc - compile a program against klibc SYNOPSIS
klcc [gcc options] [-o outfile] infile... DESCRIPTION
klcc is a wrapper around gcc(1) and ld(1) which compiles and links a program against the klibc tiny C library. It supports most gcc options. Unlike gcc, klcc compiles with optimization on by default. Furthermore, the optimization level used depends on whether or not -g is speci- fied, since klcc frequently uses options in the normal case which makes debugging impossible. Therefore, compile without -g, -O, -f or -m option to use the default optimization level; this will generally result in the smallest binaries. You may want to use -s when linking, however. Use -O0 to compile without any optimization whatsoever; this may not work depending on the version of gcc used. -nostdinc allows to turn off klibc include files. Use the -shared or -static option to compile for and link against shared or static klibc. Note that shared klibc only supports running against the exact same klibc binary as the binary was linked with. In addition to standard gcc options, klcc supports options of the form -print-klibc-option, which prints the corresponding klibc configura- tion option. AUTHOR
