# THE MALLOC STORY |

|
|
# 1994: |
| 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() |
| 15 |
|
|
# |
| 16 |
|
|
# setting usemymalloc='n' was the solution back then. Later came |
| 17 |
|
|
# reports that perl would run unstable on 3.2: |
| 18 |
|
|
# |
| 19 |
|
|
# 1996: |
| 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!! |
| 28 |
|
|
# |
| 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. |
| 33 |
|
|
# |
| 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'. |
| 37 |
|
|
# |
| 38 |
|
|
# 1997: |
| 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. |
| 42 |
|
|
# |
| 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' |
| 46 |
|
|
#usemymalloc='y' |
| 47 |
|
|
# use the following two lines if you have perl5.003_22 or better and |
| 48 |
|
|
# do not encounter intermittent core dumps. |
