Bug ID: 370609
Summary: Crash with a simple template class and auto for loop
Product: clazy
Version: unspecified
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: csaba.kertesz at gmail.com
CC: smartins at kde.org
Compile the following code snippet with the bleeding edge clazy and clang 3.8
or 3.9:
clazy -std=gnu++11 -o example.cpp.o -c example.cpp
example.cpp:
#include <vector>
template <typename T>
struct Example
{
Example()
{
for (auto sample : SampleCache)
{
}
}
std::vector<float> SampleCache;
};
void CreateExample()
{
new Example<int>();
}
Reproducible: Always
Steps to Reproduce:
1. Compile example.cpp with Clazy.
Actual Results:
Crash.
Expected Results:
Clazy should not crash.
The code compiles fine with clang, only Clazy crashes.
