Indeed.

It's worse. If I comment out all ap_rflush occurrences (they seem only
used in debug mode and purely optional, I get more severe breakage:
Can't load '/home/abe/libembperl-perl/blib/arch/auto/Embperl/Embperl.so' for
module Embperl: /home/abe/libembperl-perl/blib/arch/auto/Embperl/Embperl.so:
undefined symbol: ap_hook_open_logs at

at test.pl line 1916.
Compilation failed in require at test.pl line 1916.
BEGIN failed--compilation aborted at test.pl line 1916.
Same for ap_hook_post_config and ap_rwrite. That's where I stopped
commenting out code.

Well, on s390x:
→ objdump -T /usr/sbin/apache2 | egrep
'ap_rflush|ap_rwrite|ap_hook_open_logs|ap_hook_post_config'
00000000000b0918 g DO .data 0000000000000008 Base
ap_hack_ap_hook_post_config
000000000005f288 g DF .text 00000000000000e8 Base
ap_hook_post_config
00000000000b04b8 g DO .data 0000000000000008 Base ap_hack_ap_rwrite
00000000000447d8 g DF .text 000000000000005a Base ap_rwrite
00000000000b0900 g DO .data 0000000000000008 Base
ap_hack_ap_hook_open_logs
00000000000b0498 g DO .data 0000000000000008 Base ap_hack_ap_rflush
000000000005f448 g DF .text 00000000000000e8 Base ap_hook_open_logs
0000000000044b00 g DF .text 0000000000000098 Base ap_rflush
All there. I'm confused. This also looks fine:
→ dgrep ap_rflush apache2-dev
/usr/include/apache2/http_protocol.h:AP_DECLARE(int) ap_rflush(request_rec *r);
Even if I check in which files it is present:
s390x:
→ fgrep ap_rflush -r /usr/lib/apache2
Binary file /usr/lib/apache2/modules/mod_heartmonitor.so matches
/usr/lib/apache2/modules/httpd.exp:ap_rflush
Binary file /usr/lib/apache2/modules/mod_lua.so matches
Binary file /usr/lib/apache2/modules/mod_proxy_balancer.so matches
amd64 (stretch):
# fgrep ap_rflush -r /usr/lib/apache2
Binary file /usr/lib/apache2/modules/mod_heartmonitor.so matches
/usr/lib/apache2/modules/httpd.exp:ap_rflush
Binary file /usr/lib/apache2/modules/libphp5.so matches
Binary file /usr/lib/apache2/modules/mod_proxy_balancer.so matches
Binary file /usr/lib/apache2/modules/mod_lua.so matches
For now, I'm out of ideas.
