Package: gdb
Version: 6.4.90.dfsg-1
Severity: important
I've uncovered quite a big problem in gdb when attempting to debug Java.
Firstly, here's the source code of Test.java:
class Test {
public static void
main (String[] args)
{
System.out.println ("Hello");
return;
}
}
I issue:
javac Test.java
gcj -g --main=Test -o Test Test.java
gdb Test
Now, when I try to list:

(gdb) list
1 /tmp/ccRas48v.i: No such file or directory.
in /tmp/ccRas48v.i
(gdb)
Now, this error is reproducable in the lastest in unstable as well. I
used this version to downgrade to see if the problem was still there.
The newer version this applies to is:
GNU gdb 6.6-debian

(gdb) list
1 /tmp/cc0shoGQ.i: No such file or directory.
in /tmp/cc0shoGQ.i
(gdb) quit
Now, I can temporarily fix this! If I do:
[19:56:[EMAIL PROTECTED]>tmp]$ cp Test.java /tmp/ccRas48v.i
[19:56:[EMAIL PROTECTED]>tmp]$ gdb Test

5 {
6 System.out.println ("Hello");
7
8 return;
9 }
10 }
(gdb)
It seems to not associate this temporary file it's creating with the
source. I think it's strange it's looking for a temporary file in the
first place.
Good luck!
