Package: libgcj6
Version: 4.0.2-7
Severity: important
For some reason, attempting to convert decimal strings that correspond
to numbers below a certain threshold (between 4.24374e-214 and
4.24375e-214) to doubles (which should have an appreciably wider
range) ends up segfaulting within the guts of libgcj:
$ cat DoubleConvTest.java
class DoubleConvTest {
public static void main(String[] args) {
String s = args[0];
System.out.print("in: " + s + "\n");
Double d = new Double(s);
System.out.print("out: " + d + "\n");
}
}
$ gcj -g --main=DoubleConvTest DoubleConvTest.java -o DoubleConvTest
$ gdb --args ./DoubleConvTest 4e-214

Program exited with code 01.
The same lossage occurs when compiling to bytecode and running it with
gij.
This is causing kaffe to FTBFS on amd64, because it cannot compile the
definition of java.lang.Double.MIN_VALUE. (Likewise for ikvm, but
that's been FTBFSing lately for unrelated reasons, so it's unclear how
much fixing this would help with that.)
