>Description:
When the max. Data Size exceeds more than 1GB (1GB is still fine), then
sys/kern/imgact_elf.c has trouble exec()'ing Wine. This also manifests
itself in ldd(1) crashing on the Wine binary.
>How-To-Repeat:
Set kern.maxdsiz="1342177280" in /boot/loader.conf, run wine or
ldd /usr/local/bin/wine. 

% ldd `which wine`
/usr/local/bin/wine:
ELF interpreter /libexec/ld-elf.so.1 not found
/usr/local/bin/wine: signal 6

A maxdsiz of 1073741824 will work just fine, but YMMV.
% ldd `which wine`
/usr/local/bin/wine:
        libwine.so.1 => /usr/local/lib/libwine.so.1 (0xbbf37000)
        libc.so.6 => /lib/libc.so.6 (0xbbf4f000)

Note that using plain limit won't do. You have to reboot.

Now, I initially had a dsize of 2GB and since Wine tries something
funky with it's heap at 0x80000000 I thought this was it. But just
setting dsize somewhat above 1GB will trigger this too. Rather odd.
