So, here is a patch to fix the issue with the GNU build attached. An
essential part of NLM dump (unfixed) shows the problem:
DATA:00012BA0 = config_log_module
DATA:00012C20 = asis_module
DATA:00012CA0 = imap_module
DATA:00012DA0 = setenvif_module
---
DATA:00013DF0 = ap_server_post_read_config
DATA:00013E20 = ap_server_config_defines
DATA:00013E60 = ap_coredump_dir
DATA:00015E60 = ap_lock_fname
DATA:00015E80 = ap_bind_address
DATA:00015F60 = ap_server_pre_read_config
Data Size: 00013220 ( 78368)
All records with offset outside of data size boundary are causing this:
SERVER-5.00-1554: Invalid public record offset in load file.
Module APACHEC.NLM NOT loaded
I'm using the ApacheCore.imp as export file when building apachec.nlm
and suppose it's correct bahaviour...
Pavel
P.S.: An enhancement of the nlmconv utility is much accurate than "fix",
that's what I exactly meant.
