--- Comment #5 from Andreas K. Huettel <dilfridge at gentoo dot org> ---
I tried bisecting this, and the result is ... puzzling.
a291237b628f419d7f7ac264dd7b42947b565222 is the first bad commit
commit a291237b628f419d7f7ac264dd7b42947b565222

Remove simple ranges from trailing zero bitmasks.
During the intersection operation, it can be helpful to remove any
low-end ranges when the bitmask has trailing zeros. This prevents
obviously incorrect ranges from appearing without requiring a bitmask
check.
* value-range.cc (irange_bitmask::adjust_range): New.
(irange::intersect_bitmask): Call adjust_range.
* value-range.h (irange_bitmask::adjust_range): New prototype.
