## ------------------------------------------- ##
|
||||
|
||||
# In 1992, Michael Bushnell (now Thomas Bushnell <thomas@gnu.ai.mit.edu>)
|
||||
# devised a test for avoiding HP/UX malloc and using GNU malloc instead.
|
||||
# Bruno Haible <haible@ma2s2.mathematik.uni-karlsruhe.de> recycled this
|
||||
# test for CLISP Common LISP and extended it to cover broken mallocs from
|
||||
# Sun and SGI. I (<pinard@iro.umontreal.ca>) 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 <john@bitsmart.com>).
|
||||
|
||||
# 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.
