That's strange. We add buttons with TB_ADDBUTTONSW internally during
CreateToolbarEx, separators' iString-s are handled with a special path:
---
        if (btnPtr->fsStyle & BTNS_SEP)
            btnPtr->iString = -1;
---
So we don't depend on garbage passed here for iString.

Anyway I can't crash it on wine-1.1.31-159-ge52115d (on startup I mean), I'm
trying version 2.0f.
