Bug #: 12817
Summary: Assertion `NextFieldOffset <= RecordSize && "Size
mismatch!"'
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]

Created attachment 8549
--> http://llvm.org/bugs/attachment.cgi?id=8549
reduced test case (provided by Craig Schroeder)
Running clang trunk on:
struct s1 {long a[-6 / (8 * sizeof (long))];};struct s2 {int b;struct
s1 c;};struct s3 {struct s2 d[1];};struct s3 * e;
results in:
clang:
/src/llvm-trunk-writable/tools/clang/lib/CodeGen/CGRecordLayoutBuilder.cpp:868:
void<unnamed>::CGRecordLayoutBuilder::AppendTailPadding(clang::CharUnits):
Assertion `NextFieldOffset <= RecordSize && "Size mismatch!"' failed.
FWIW, gcc 4.4.3 accepts this without error or warning.
