Bug ID: 52011
Summary: A/F: `SI != MemberOffsets.begin() && "Offset not in
structure type!"' after commit e9e1d4751b54
Product: new-bugs
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

Internally we run the GDB test suite, and one of the tests within it started to
hit an assertion failure which I bisected down to commit
e9e1d4751b54126743ed72b1a9178ee51200acf6.
I reduced the test down to the following code:
/* repro.c */
struct {
float a;
struct {};
double b
} __trans_tmp_1() {
}
Compiling using a compiler that includes
e9e1d4751b54126743ed72b1a9178ee51200acf6 with only "-c" is enough to reproduce
the failure:
$ ~/src/upstream/e9e1d4751b54126743ed72b1a9178ee51200acf6-linux/bin/clang -c
repro.c
repro.c:4:11: warning: expected ';' at end of declaration list
double b
^
;
repro.c:6:1: warning: non-void function does not return a value [-Wreturn-type]
}
^
clang: /home/dyung/src/upstream/llvm_clean_git/llvm/lib/IR/DataLayout.cpp:85:
unsigned int llvm::StructLayout::getElementContainingOffset(uint64_t) const:
Assertion `SI != MemberOffsets.begin() && "Offset not in structure type!"'
failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
