Subject [jira] Commented: (HARMONY-5305) [drlvm][jit][EUT] regression in jdtdebug in Linux x86_64
Date Mon, 17 Dec 2007 13:03:45 GMT

Gregory Shimansky commented on HARMONY-5305:
--------------------------------------------

I am just curious about the way how garbage happened to be in RAX upper half. Looking at Eclipse
code for getExtendedEnd RAX holds the value of "range" variable. As far as I understand it
shouldn't have a value of 0x100000001 in any place of the execution.

        public int getExtendedEnd(ASTNode node) {
                int end = node.getStartPosition() + node.getLength();
                if (this.trailingPtr >= 0) {
                        long range = -1;
                        for (int i=0; range<0 && i<=this.trailingPtr; i++) {
                                if (this.trailingNodes[i] == node) range = this.trailingIndexes[i];
                        }
                        if (range >= 0) {
                                Comment lastComment = this.comments[(int) range];
                                end = lastComment.getStartPosition() + lastComment.getLength();
                        }
                }
                return end-1;
        }

> The jdtdebug suite start hanging on Linux x86_64. 
> The issue migt be the same to HARMONY-5303, still CC start repoting this crash earlier
