Version: 2.036

Filing these as one bug report since they probably have the same underlying
cause (can't tell for sure since CustomFloat relies on BitFields, and debugging
string mixins that I didn't write myself is incredibly hard)
import std.stdio, std.numeric;
alias CustomFloat!(1, 13, 2) F;
void main() {
F num = F(0.314);
writeln(num.get!float);
}
Compile w/ -O -inline -release. Result: Compile time error:
numeric.d(206): Error: variable result used before set
Compile with default compiler settings. Result: Compiles, assert failure:
core.exception.asserter...@std.numeric(115): Assertion failure
Compile with -release to disable asserts but without -O to prevent compiler
from noticing variable used before set. Runs, produces incorrect result.
Prints:
1.74431e-39
