The stack trace *is* recorded, but isn't propagated properly across places, even in SVN HEAD. See http://jira.codehaus.org/browse/XTENLANG-540 . One solution is to attach to the process with gdb before the exception occurs, and set a breakpoint in x10aux::throwException(). This will let you see the stack trace for the invalid access. You should be able to find the corresponding line of X10 code from the comments in the generated C++ code. > Is there a function, macro, ... that can inform where a variable > (scalar or component of an array) is located ? UPC for example, has > such a function (upc_threadof). For any Ref, you can access the "location" property, which is of type Place. You can get the place id by accessing the "id" property of that Place value. > Also, the c++ compiler frequently issue the following warnings : > .../include/x10aux/bootstrap.h:104: warning : format ‘%ld’ expects > type ‘long int’, but argument 3 has type ‘x10_int’ > .../include/x10aux/bootstrap.h:113: warning : format ‘%ld’ expects > type ‘long int’, but argument 3 has type ‘x10_int’ > .../include/x10aux/bootstrap.h:126: warning : format ‘%ld’ expects > type ‘long int’, but argument 3 has type ‘x10_int’ > > Normally warnings like these ones are harmless, but one never knows.
