edit: actually xmalloc and xfree are defined as #define xmalloc ruby_xmalloc #define xfree ruby_xfree

  That's actually fascinating. I wonder if anyone has background on this...any comments I see are in Japanese.

    Replacing malloc/calloc/free etc an application-specific xmalloc/xcalloc/xfree is seemingly a fairly common pattern. There's one example in libiberty[0] (-liberty, get it?) where, for instance, the return value of malloc is checked for NULL and the program terminates if so.
