[llvm-bugs] [Bug 31497] New: ctype_byname::do_widen widens invalid characters to WEOF.

This is probably the incorrect behavior, even if libstdc++ also does it. Instead do_widen should return the original value when btowc returns WEOF. -- You are receiving this mail because: You are on the CC list for the bug. ___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs

However I don't think having a conversion to void* is much better. So in r290750 I implemented it using a pointer to member function instead. That way it should only really convert to bool. -- You are receiving this mail because: You are on the CC list for the bug. ___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs
[llvm-bugs] [Bug 31498] New: clang-check static analyzer crashes when processing union
https://llvm.org/bugs/show_bug.cgi?id=31498
Bug ID: 31498
Summary: clang-check static analyzer crashes when processing
union
Product: new-bugs
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: adam...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Created attachment 17792
--> https://llvm.org/bugs/attachment.cgi?id=17792&action=edit
Sample program
Tested on Windows. Llvm build snapshot: 288665
If I run clang-check with command:
clang-check.exe test.cpp -analyze
On the code below:
void* __cdecl memcpy(void* _Dst, void const* _Src, size_t _Size);
struct Test{
union{
char* heapbuf;
char stackbuf[8];
} data;
unsigned size;
Test() = default;
Test(const Test& other){
size = other.size;
memcpy(data.stackbuf, other.data.stackbuf, size);
data.stackbuf[size] = 0;
}
};
Test read(){
return Test();
}
int main(){
Test b = read();
char* data = new char[b.size];
return 0;
}
Then I receive error message:
Running without flags.
Assertion failed: T::isKind(*this), file
