[Libreoffice] UNO related crashes on NetBSD

Hi,

The latest -master version crashes reliably on NetBSD (i386 and amd64).

The primary suspect is UNO, the 'uno' binary segfaults:

The symptoms are the same as in this Gentoo/arm bug:

https://bugs.gentoo.org/show_bug.cgi?id=370975

In July, the amd64 version didn't crash, but I may just have been lucky.

One user tried to debug the i386 binary; this is the gdb output:

Does any UNO specialist have a clue what to look for ?
