13 # the simple program `for ($i=1;$i<38771;$i++){$t{$i}=123}' fails
14 # with Larry's malloc on NS 3.2 due to broken sbrk()
16 # setting usemymalloc='n' was the solution back then. Later came
17 # reports that perl would run unstable on 3.2:
20 # From about perl5.002beta1h perl became unstable on the
21 # NeXT. Intermittent coredumps were frequent on 3.2 OS. There were
22 # reports, that the developer version of 3.3 didn't have problems, so it
23 # seemed pretty obvious that we had to work around an malloc bug in 3.2.
24 # This hints file reflects a patch to perl5.002_01 that introduces a
25 # home made sbrk routine (remember, NeXT's sbrk _never_ worked). This
26 # sbrk makes it possible to run perl with its own malloc. Thanks to
27 # Ilya who showed me the way to his sbrk for OS/2!!
29 # The whole malloc desaster lead to a failing gdbm test. It is far
30 # beyond my understanding, why GDBM_File breaks with the "fix", but in
31 # general I consider it better to have a working perl with broken GDBM
32 # than no perl at all.
34 # So, this hintsfile is using perl's malloc. If you want to turn
35 # perl's malloc off, you need to remove '-DUSE_PERL_SBRK'
36 # from the ccflags and set usemymalloc to 'n'.
39 # From perl5.003_22 the malloc bug has no impact any more. We can run
40 # a perl without a special sbrk. Apparently Chip Salzenberg, the hero
41 # of 5.004 anyway, earned another trophy during Australien Open.
43 # use the following two lines to enable USE_PERL_SBRK. Try this if you
44 # encounter intermittent core dumps:
45 #ccflags='-DUSE_NEXT_CTYPE -DUSE_PERL_SBRK'
47 # use the following two lines if you have perl5.003_22 or better and
48 # do not encounter intermittent core dumps.
