Bug ID: 23165
Summary: abort with "pure virtual method called", when a
virtual function is called on a POD temporary passed
as an argument (in program compiled w/ clang trunk
-std=c++11)
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Created attachment 14171
--> https://llvm.org/bugs/attachment.cgi?id=14171&action=edit
C++ testcase
STR:
1. Compile attached program using clang 3.7 with -std=c++11:
clang++-3.7 -std=c++11 test.cpp
(Or use -std=gnu++0x)
2. Run the resulting a.out
ACTUAL RESULTS:
The program aborts with:
> pure virtual method called
> terminate called without an active exception
> Aborted (core dumped)
EXPECTED RESULTS:
No abort; virtual function should run successfully.
I get EXPECTED RESULTS if I drop the "-std=c++11" command-line argument. I also
get EXPECTED RESULTS from clang++-3.6 (with the c++11 command-line argument
included). So this is a regression, or at least a behavior-change.
