Bug ID: 27840
Summary: Compilation triggers a compiler bug - it asked to
report to llvm.org
Product: clang
Version: 3.7
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: uri at ll.mit.edu
CC: dgregor at apple.com, llvm-bugs at lists.llvm.org
Classification: Unclassified
Mac OS X 10.11.5, Xcode-7.3.1, Macports-2.3.4.
The problem is with Macports-installed clang-3.7 (which was built using
Xcode-7.3.1).
Here's the screen log:
clang++-mp-3.7 -maes -mpclmul -mrdrnd -msse2 -mssse3 -msse4.1 -msse4.2
-std=c++11 -ffunction-sections -fdata-sections -O3 -fPIC -march=native -pipe -c
integer.cpp
Assertion failed: (BB->getTerminator()->getNumSuccessors() == 1 && "Should have
a single succ!"), function SplitEdge, file
