Hi, when compiling some Java code with ECJ 3.4.1 as the compiler running on Cacao 0.99.4 and GNU Classpath 0.98 I get the following error message. | javac -sourcepath src/java -cp /home/rob/oe/chinook/tmp/staging/x86_64-linux/usr/share/java/oro.jar -d build `find src/java/org -name '*.java'` | LOG: [0x00007fe1a505c950] md_signal_handler_sigill: Unknown illegal instruction at 0x7fe1a5072903 | LOG: [0x00007fe1a505c950] Aborting... At this time I can only say that it does not happen if I switch to Cacao 0.99.3. I will provide disassembler output and traces tomorrow evening.
That is strange, it surely looks like the trap race condition we were having (Bug #85), but that is (still) fixed in the stable branch. I am really interested in the disassembler output of the failing illegal instruction. Another reason for me to finish the new-trap-decoding branch.
I have added 0.99.4 to the list of available versions in our Bugzilla and adapted this bug accordingly.
I tried to reproduce the problem with a VM that was build with --enable-disassembler. The initial problem happened as part of a larger build inside an OpenEmbedded operation. Unfortunately I was not able to get the error to occur again. ECJ (on Cacao+Classpath) does the compilation just fine. As such I mark this PR as INVALID. If it the problem occurs again I will reopen this and provide disassembly output immediately.
