[Bug target/29805] New: Wrong code compiling java/typeck.c

["daney at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

With a bootstrap build of the 4.2 branch jc1 gets SIGSEGV compiling
newarray_overflow.java from the java testsuite.

This is the command to reproduce:

./jc1 -fclasspath=../mipsel-unknown-linux-gnu/libjava/libgcj-4.3.0.jar
../../gcc/libjava/testsuite/libjava.lang/newarray_overflow.java
-fhash-synchronization -fno-use-divide-subroutine -fuse-boehm-gc
-fnon-call-exceptions -fkeep-inline-functions -quiet -dumpbase
newarray_overflow.java -march=mips32 -msoft-float -mno-shared -auxbase
newarray_overflow -g1 -version -o /junk/newarray_overflow.s

If I recompile java/typeck.c with -O0 there is no SIGSEGV

The same thing on the trunk (4.3) except 'internal compiler error: tree check'
instead of SIGSEGV.

A cross compiler built on i686-pc-linux-gnu does not have the problem.

Looking at gcc-testresults leads me to think that this has been happening since
at least June 2006.
