ep-engine dies with segmentation fault on warmup

The bucket has few million of items and I'm pretty sure few previous warmups worked fine. But this time (perhaps just luck or maybe there's some disk state that's damaged). I'm getting a continuous crashes:

warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
