/* * * Date: 10 February 2003 * SUMMARY: Object.toSource() recursion should check stack overflow * * See http://bugzilla.mozilla.org/show_bug.cgi?id=192465 * * MODIFIED: 27 February 2003 * * We are adding an early return to this testcase, since it is causing * big problems on Linux RedHat8! For a discussion of this issue, see * http://bugzilla.mozilla.org/show_bug.cgi?id=174341#c24 and following. * * * MODIFIED: 20 March 2003 * * Removed the early return and changed |N| below from 1000 to 90. * Note |make_deep_nest(N)| returns an object graph of length N(N+1). * So the graph has now been reduced from 1,001,000 to 8190. * * With this reduction, the bug still manifests on my WinNT and Linux * boxes (crash due to stack overflow). So the testcase is again of use * on those boxes. At the same time, Linux RedHat8 boxes can now run * the test in a reasonable amount of time.
