This specifies a sub-bug of 18212. The test-case is simple, not the severity!

Given are 2 independet(!) and (almost) empty classes: A1 and A2. A1 has the
main() method. A1 is in jar J1, A2 in jar J2.

The bug: Compiling the jar J1 by giving the output file by -o fails, when
compiled with J2.

failing:
gcj -o foo --classpath=J2.jar:. --main=A1 J1.jar J2.jar
gcj -o foo --classpath=J2.jar:J1.jar --main=A1 J1.jar J2.jar

working:
gcj -o foo --main=A1 J1.jar J2.jar
gcj -o foo --classpath=J2.jar:. --main=A1 J1.jar
gcj -o foo --main=A1 J1.jar

gcj --classpath=J2.jar:. --main=A1 J1.jar J2.jar
gcj --classpath=J2.jar:. --main=A1 J1.jar
gcj --main=A1 J1.jar J2.jar
gcj --main=A1 J1.jar

When failing, it reports:

java/awt/Component.java: In class `java.awt.Component':
java/awt/Component.java: In method `java.awt.Component.eventTypeEnabled(int)':
java/awt/Component.java:4127: error: expected type 'int' but stack contains 'void'
java/awt/Component.java:4127: error: verification error at PC=311
java/awt/Component.java:4127: error: types could not be merged
ObjectInputStream.java: In class `java.io.ObjectInputStream$3':
ObjectInputStream.java: In method
`java.io.ObjectInputStream$3.getField(java.lang.String,java.lang.Class)':
ObjectInputStream.java:1257: error: verification error at PC=45
ObjectInputStream.java:1257: error: loading local variable 6 which has unknown type
java/lang/Class.java:0: confused by earlier errors, bailing out

The source codes:

1) A1.java
public class A1 {
    
    public static void main(String args[]) {
    }    
}

2) A2.java:
public class A2 {
}
