Not sure. How can I determine how much memory a process will allocate after
loading into memory and resolving all dynamic link library references?

sysctl:
---8<---
[...]
proc.curproc.rlimit.filesize.soft = unlimited
proc.curproc.rlimit.filesize.hard = unlimited
proc.curproc.rlimit.datasize.soft = 33554432
proc.curproc.rlimit.datasize.hard = 134217728
proc.curproc.rlimit.stacksize.soft = 2097152
proc.curproc.rlimit.stacksize.hard = 33554432
proc.curproc.rlimit.coredumpsize.soft = unlimited
proc.curproc.rlimit.coredumpsize.hard = unlimited
proc.curproc.rlimit.memoryuse.soft = 136052736

amiga/include/vmparam.h has just 6MB for MAXTSIZ. 128MB for MAXDSIZ and 32MB
for MAXSSIZ.

The size of cc1's text segment seems larger than 6MB:

Is this the reason? Then Amiga is the only affected port, besides Sun2
(2MB). Maybe I should go to 16MB like Atari did.
