Bug ID: 19442
Summary: warning: implicit conversion changes signedness:
'long' to 'int'
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs

Testcase
The below small testcase causes -Wsign-conversion to print a (to me)
nonsensical warning message: "warning: implicit conversion changes signedness:
'long' to 'int'".
void f(void)
{
unsigned int mask = 1;
long value = 1;
int result = value & mask;
}
The warning is correct in that there is an implicit sign conversion going on,
but it's not between (signed) long and (signed) int, like the warning message
says.
This message has been the same since at least 3.0.
