Crash or strange result when printing f32 #112
Description
Not sure if this is the place for this kind of issue...
During #93 (see comment)I discovered that the following code snippet seems to crash on ESP32-S3 and likely ESP32(have not tested the last example on ESP32 yet):
fn main() -> anyhow::Result<()> {
esp_idf_sys::link_patches();
let v = 16.0;
println!("f32 literal is={v}");
let v = f32::from(16_u16);
println!("Converting the number seems to work");
println!("from u16 to f32 is={v}"); // <--- Boom
loop {}
}Also note in the log from where I first discovered the problem that there is weird output for several of the "duty" lines before the crash. From what I can tell the actual number printed is important. 16 seems to be the smallest integer >= 0 that when converted to f32 causes a crash. Some of the smaller values only causes weird output.
Somehow I can not seem to reproduce the problem by using a f32 literal(not the exact same value due to floating point magic?)
Compiling in release mode and using IDF v4.4
