After several test and simplifications, it appears that the conditions of this failure is: - Use the -findirect-dispatch flag - Use the --jni flag - The class contains at last one jni method - The class contains at last one constructor If one this condition is unmet, the compilation succeed. I tried compilling the .java, .class and .jar file, each time with the same result. Using strace the segfaulting program seems to be jc1 I have the same result with: - gcj-4.2 (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu6) - gcj-4.3 (GCC) 4.3.0 [Compiled from sources] -- Compiler output: $ gcj-4.3 -findirect-dispatch --jni Test.java -c Test.java: In class 'Test': Test.java: In method 'foo()': Test.java:0: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
