Root cause is that offset_region::get_{byte,bit}_size_sval were attempting to compute the size that's valid to access, rather than the size of the access attempt. Fixed by removing these vfunc overrides from offset_region as the base class implementation does the right thing. gcc/analyzer/ChangeLog: PR analyzer/111266 * region.cc (offset_region::get_byte_size_sval): Delete. (offset_region::get_bit_size_sval): Delete. * region.h (region::get_byte_size): Add comment clarifying that this relates to the size of the access, rather than the size that's valid to access. (region::get_bit_size): Likewise. (region::get_byte_size_sval): Likewise. (region::get_bit_size_sval): Likewise. (offset_region::get_byte_size_sval): Delete.
