Package: gcj-4.0
Version: 4.0.2-5j2
Severity: normal
GCJ fails with message internal compiler error: in generate_bytecode_insns,
at java/jcf-write.c:1960 when trying to compile something like "1++".
Javac from SableVM reports semantic error on this.
This problem exist in gcc-snapshot too.
To reproduce bug, follow this instructions:
$ cat << EOF > gcjbug.java
class gcjbug {
public static void main (String [] p) {
System.out.println(1++);
}
}
EOF
$ gcj -C gcjbug.java
gcjbug.java: In class 'gcjbug':
gcjbug.java: In method 'gcjbug.main(java.lang.String[])':
gcjbug.java:3: internal compiler error: in generate_bytecode_insns, at
java/jcf-write.c:1960
Please submit a full bug report,
with preprocessed source if appropriate.
