- ## From Franc,ois Pinard ##
- ## ------------------------------------------- ##
- # In 1992, Michael Bushnell (now Thomas Bushnell <[email protected]>)
- # devised a test for avoiding HP/UX malloc and using GNU malloc instead.
- # Bruno Haible <[email protected]> recycled this
- # test for CLISP Common LISP and extended it to cover broken mallocs from
- # Sun and SGI. I (<[email protected]>) reworked it a little so
- # it is independent of config.guess, and overridable by the installer.
- # On IRIX 5.2, libc malloc is broken, but the -lmalloc one was usable.
- # So in my packages, I once unconditionally used -lmalloc if it existed.
- # This does not do anymore, because the -lmalloc malloc is broken on
- # Solaris 2.4 to 2.5.1 (alignment is 4 bytes instead of 8 bytes, as
- # reported by John Wells <[email protected]>).
- # Bruno also notes: "HP-UX has two different malloc() implementations.
- # Both are broken. When used with CLISP, the one in the default libc.a
- # leads to a SIGSEGV, the one in libmalloc.a leads to a SIGBUS. The SunOS
- # 4.1.1 malloc() breaks when used by CLISP's generational GC. The IRIX
- # 5.2 malloc() breaks when used by CLISP's generational GC."
- # If the installer does not give a preference, we use the included GNU
- # malloc if we have the slightest doubt that malloc could be broken, this
- # includes cross compilation, and *all* HP/UX, SunOS or IRIX systems.
- # It is crude indeed, but I just do not have enough information for truly
- # benchmarking malloc in all cases, but want safe packages nevertheless.
