Hi,

gij-4.6 just segfault for any java code under kfreebsd-amd64 (whereas it works 
fine under kfreebsd-i386). I tested all this under asdfasdf.debian.net 
porterbox.

Here is some example :
Test.java
----------------------------
public class Test {
public static void main(String[] args) {
System.out.println("OK");
}
}
----------------------------
$> /usr/lib/jvm/java-gcj-4.6/bin/javac Test.java
$> /usr/lib/jvm/java-gcj-4.6/bin/java Test
Segmentation fault
$>

Here is ktrace output for last fopen before crash :
----------------------------
 59454 gij-4.6  CALL  open(0x648bc0,O_RDONLY|O_LARGEFILE,<unused>0)
 59454 gij-4.6  NAMI  "/var/lib/gcj-4.6/classmap.db"
 59454 gij-4.6  RET   open 5
 59454 gij-4.6  CALL  stat(0x7fffffffe1a0,0x7fffffffe110)
 59454 gij-4.6  NAMI  "/var/lib/gcj-4.6/classmap.db"
 59454 gij-4.6  STRU  invalid record
 59454 gij-4.6  RET   stat 0
 59454 gij-4.6  CALL  fstat(0x5,0x7fffffffe1e0)
 59454 gij-4.6  STRU  invalid record
 59454 gij-4.6  RET   fstat 0
 59454 gij-4.6  CALL  mmap(0,0x4000,PROT_READ,MAP_PRIVATE,0x5,0)
 59454 gij-4.6  RET   mmap 34366324736/0x800648000
 59454 gij-4.6  PSIG  SIGSEGV SIG_DFL
----------------------------

So I thought it was linked to some previous mmap issues we already had (see 
[1] or [2]) so I tried to skip mmap'ing of this classmap.db file (used for AOT-
Compile).
Sadly, it's not better :
$> /usr/lib/jvm/java-gcj-4.6/bin/java -Dgnu.gcj.precompiled.db.path= Test
Segmentation fault
$>

Ktrace :
----------------------------
 75773 gij-4.6  NAMI  "/home/drazzib/Test.class"
 75773 gij-4.6  STRU  invalid record
 75773 gij-4.6  RET   stat 0
 75773 gij-4.6  CALL  read(0x5,0x694c0c,0x194)
 75773 gij-4.6  GIO   fd 5 read 404 bytes
[...]
 75773 gij-4.6  RET   read 404/0x194
 75773 gij-4.6  CALL  close(0x5)
 75773 gij-4.6  RET   close 0
 75773 gij-4.6  PSIG  SIGSEGV SIG_DFL
----------------------------

Did someone have any clue ?
