Bug ID: 26787
Summary: [ms][EH] Clang cannot find appropriate catch statement
for a throw
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
!- Clang incorrectly works with EH on Windows and cannot find appropriate catch
statement for a throw function, all other compilers work correctly.
Moreover clang on Linux works correctly as well. This problem can be related to
incorrect work of function-try-block -!
=====Environment===========
OS: Windows
Lang: c++
=====Small Reproducer======
#include <stdio.h>
struct A {
~A () { throw 1; }
};
struct B : public A {
~B()
try { printf("B destructed\n"); }
catch(int j) { printf("Caught %d in ~B\n", j); }
};
int main()
{
try { B b; }
catch (int j) {}
return 0;
}
$ clang test.cpp -o out.exe
$./out.exe
=========Behavior==========
>>> clang on Win:
B destructed
$ echo $?
9
>>> clang on Lin, gcc, MSVC, Intel icc:
B destructed
Caught 1 in ~B
0
