Description Arie Bikker 2022-06-14 13:57:13 UTC 
Created attachment 234678 [details]
Patch arraysize receiving argument sysctl

both binary package and ports compiled version fail

$ wmmemload
Abort

leaving line in /var/log/messages:

Jun 14 15:35:33 azd wmmemload[55487]: stack overflow detected; terminated
Jun 14 15:35:33 azd kernel: pid 55487 (wmmemload), jid 0, uid 1001: exited on signal 6

Problem seems to be fixed size of mib array in src/mem_freebsd.c
For descendants of "vm.swap_info" array size should be 3

Comment 2 Marco Beishuizen 2024-03-10 14:18:01 UTC 
The patch from Arie didn't build with the "char mib_base = "vm.swap_info";" line in it so removed that and left the increase from 2 > 3 of "int mib[]"

Could you please create a patch on the ports tree?
