I think that's what happen:
The X10 compiler created the C++ files, and then it runs the C++ compiler
(we call it a post-compiler) from within Java, and if the return code was
not zero, then it outputs the C++ compiler's output. And your C++ compiler
apparently created a LOT of output (that caused the OutOfMemory).
You can use "-c" to specify another post-compiler.
Runtime runtime = Runtime.getRuntime();
Process proc = runtime.exec(cxxCmd, null,
options.output_directory);
InputStreamReader err = new
InputStreamReader(proc.getErrorStream());
String output = null;
try {
char[] c = new char[72];
int len;
StringBuffer sb = new StringBuffer();
while((len = err.read(c)) > 0) {
sb.append(String.valueOf(c, 0, len)); *// threw a
OutOfMemoryError*
}
