Summary: Multi-dimensional aggregate assert failure in
SelectionDAGLowering
Product: libraries
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P2
Component: Common Code Generator Code
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Inserting at certain offsets in a multi-dimensional aggregate tickles an
index-related assert-failure in SelectionDAGLowering:
%i = insertvalue [2 x [2 x i32]] undef, [2 x i32] undef, 1
It doesn't matter whether the operands are undef, but the 1 index is
significant.
Assertion failed: (Begin + idx <= End), function operator[], file
llvm-trunk/include/llvm/ADT/SmallVector.h, line 127.
