While attempting to compile gcj, it throws, among other things, a segfault that I have traced back to line 536 of gcc/java/typeck.cc (on my msterstable branch https://github.com/Zopolis4/gcj/tree/msterstable). The segfault is due to the DECL_NAME call, which then fails the contains_struct_check and causes a segfault. According to 5a5e7deb5f93f04e027fd5baa1876370d6d6697f and 78fcec3fee63f10cfde06c252fc391e768c64b12, the correct fix would be to wrap the call in DECL_NAME, no? Yet that just causes the contains_struct_check to fail on the if DECL_NAME (TYPE_NAME (type)) call. What is the proper way to solve this? libtool: compile: /home/zopolis4/gcjbuild/./gcc/gcj -B/home/zopolis4/gcjbuild/x86_64-pc-linux-gnu/libjava/ -B/home/zopolis4/gcjbuild/./gcc/ -B/usr/local/x86_64-pc-linux-gnu/bin/ -B/usr/local/x86_64-pc-linux-gnu/lib/ -isystem /usr/local/x86_64-pc-linux-gnu/include -isystem /usr/local/x86_64-pc-linux-gnu/sys-include -fomit-frame-pointer -Usun -fclasspath= -fbootclasspath=/home/zopolis4/gcjbuild/../gcj/libjava/classpath/lib --encoding=UTF-8 -Wno-deprecated -fbootstrap-classes -g -O2 -c -fsource-filename=/home/zopolis4/gcjbuild/x86_64-pc-linux-gnu/libjava/classpath/lib/classes -MT gnu/awt/j2d.lo -MD -MP -MF gnu/awt/j2d.deps @gnu/awt/j2d.list -fPIC -o gnu/awt/.libs/j2d.o /home/zopolis4/gcj/libjava/gnu/awt/j2d/AbstractGraphicsState.java: In class 'gnu.awt.j2d.AbstractGraphicsState': /home/zopolis4/gcj/libjava/gnu/awt/j2d/AbstractGraphicsState.java: In method 'gnu.awt.j2d.AbstractGraphicsState.clone()': In file included from <built-in>:351: /home/zopolis4/gcj/libjava/gnu/awt/j2d/AbstractGraphicsState.java:133: internal compiler error: Segmentation fault 133 | return super.clone (); | 0xda20cf crash_signal /home/zopolis4/gcjbuild/../gcj/gcc/toplev.cc:322 0x86be61 contains_struct_check(tree_node*, tree_node_structure_enum, char const*, int, char const*) /home/zopolis4/gcjbuild/../gcj/gcc/tree.h:3621 0x86be61 build_java_signature(tree_node*) /home/zopolis4/gcjbuild/../gcj/gcc/java/typeck.cc:536 0x86b7c4 shallow_find_method /home/zopolis4/gcjbuild/../gcj/gcc/java/typeck.cc:650 0x86b9f6 lookup_do /home/zopolis4/gcjbuild/../gcj/gcc/java/typeck.cc:756 0x864d8a expand_invoke /home/zopolis4/gcjbuild/../gcj/gcc/java/expr.cc:2462 0x866193 process_jvm_instruction(int, unsigned char const*, long) /home/zopolis4/gcjbuild/../gcj/gcc/java/javaop.def:292 0x86884f expand_byte_code(JCF*, tree_node*) /home/zopolis4/gcjbuild/../gcj/gcc/java/expr.cc:3244 0x87f494 parse_class_file /home/zopolis4/gcjbuild/../gcj/gcc/java/jcf-parse.cc:1658 0x87fd2d java_parse_file() /home/zopolis4/gcjbuild/../gcj/gcc/java/jcf-parse.cc:1976 Please submit a full bug report, with preprocessed source (by using -freport-bug).
