Comment # 2 on bug 1100690 from Thomas B. R�cker

Unfortunately that doesn't seem to have addressed it.
(windows:mingw:win32) mingw32-cross-nsis-3.03-1.31.x86_64.rpm

yet:
[    9s] + makensis icecast.nsis -V4
[    9s] Processing config: /etc/nsisconf.nsh
[    9s] Processing script file: "icecast.nsis" (UTF8)
[    9s] /var/tmp/rpm-tmp.ATM0QG: line 33:  1804 Segmentation fault     
makensis icecast.nsis -V4
[    9s] error: Bad exit status from /var/tmp/rpm-tmp.ATM0QG (%build)

Unfortunately I have no other ideas than to start installing all remaining
packages of a headless opensuse to see which one makes it change behaviour.
