--- Comment #5 from Vittorio Zecca <zeccav at gmail dot com> ---
I confirm I get the ICE on trunk 260152 and on a sanitized version I also get

../../gcc/gcc/tree-ssa-strlen.c:721:11: runtime error: member access
within null pointer of type 'struct strinfo'

Thank you for the very useful reduction, Martin.
