Summary: ice in intersect_range_with_nonzero_bits, at
tree-vrp.c:213
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

C source code
For the attached code, on recent gcc trunk, with compiler flags -O3 and
-fwrapv,
does this:
src/client/refresh/files/stb_image.h:2815:17: internal compiler error: in
intersect_range_with_nonzero_bits, at tree-vrp.c:213
0x6b5d59 intersect_range_with_nonzero_bits(value_range_type,
generic_wide_int<wide_int_storage>*, generic_wide_int<wide_int_storage>*,
generic_wide_int<wide_int_storage> const&, signop)
../../trunk/gcc/tree-vrp.c:213
0x18f51c0 split_constant_offset_1
../../trunk/gcc/tree-data-ref.c:728
0x18f55a6 split_constant_offset(tree_node*, tree_node**, tree_node**)
../../trunk/gcc/tree-data-ref.c:782
0x18f4e34 split_constant_offset_1
../../trunk/gcc/tree-data-ref.c:617
I will have my usual go at reducing the code and finding a range
of revisions for the problem.
