Bug #: 12317
Summary: segmentation fault while compiling template class with
inner class and enum
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++

Hi clang developers,
while compiling the following code I get a segfault.
clang_crash.cpp:
template <class A>
class Outer
{
public:
class Inner
{
public:
//Inner();
enum {
VAL1 = 1
};
//static const int VAL1=1;
char b[100-VAL1];
};
Inner inner;
};
Outer<int> outer;
/usr> clang++ clang_crash.cpp
clang: error: unable to execute command: Segmentation fault
Some observations:
- removing the enum and uncommenting the "static const int VAL1" makes it work
- uncommenting the Inner() constructor causes about 20 identical errors to be
printed out:
clang_crash.cpp:8:5: error: constructor cannot be redeclared
Inner();
Afterwards, clang still segfaults.
- when the outer class isn't a template it also works
I have attached the source, preprocessed source and the run script.
clang version 3.1 (trunk 153100)
Target: x86_64-unknown-linux-gnu
Thread model: posix
Could you have a look please?
Best regards,
Martin
