This is the same as solaris-sparc64.

Thus long being 64 bits does not explain why exampleApp crashes on

solaris-sparc64 but not on linux64.

Sun provide a useful chapter in their C compiler manual that talks about

converting code from the old ILP32 (Int, Long, Pointer = 32 bits) model

to the new LP64 (Long, Pointer = 64 bits) model, which is apparently

"the creation of a consortium of companies across the industry" and thus

becoming a de-facto standard:
