             Bug #: 56372
           Summary: Missing libgcj caused ICE (stack overflow) in jc1
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: java
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: k2k@narod.ru
              Host: i686-pc-mingw32
            Target: i686-w64-mingw32, x86_64-w64-mingw32
             Build: i686-pc-mingw32


When building cross-compiler, this command caused stack overflow

i686-pc-mingw32-gcj -o ecjx.exe -findirect-dispatch
--main=org.eclipse.jdt.internal.compiler.batch.GCCMain
../../../../source/gcc-4.7.2/libjava/../ecj.jar ecjx.o

That internally calls

"t:/dvlp/mingw-w64-i686/libexec/gcc/i686-w64-mingw32/4.7.2/jc1.exe"
"../../../../source/gcc-4.7.2/libjava/../ecj.jar" "-fhash-synchronization"
"-fuse-divide-subroutine" "-fcheck-references" "-fuse-boehm-gc"
"-fkeep-inline-functions" "-quiet" "-dumpbase" "ecj.jar" "-mtune=generic"
"-march=pentium3" "-auxbase" "ecj" "-g1" "-findirect-dispatch"
"-fbootclasspath=./;T:/dvlp/mingw-w64-i686/share/java/libgcj-4.7.2.jar" "-o"
"C:\Users\UserName\AppData\Local\Temp\ccgbcsCW.s"

If libgcj-4.7.2.jar is missing than jc1.exe is closed with error (stack
overflow). Even with increased stack to 140 MB.
Situation with missing libgcj is not valid, but I believe that jc1 must print
some error message and not to crash.
