+ *
+ * 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.

+ * SUMMARY: Testing for recursion check in js_EmitTree
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=226507
+ * Igor's comments:
+ *
+ * "For example, with N in the test  set to 35, I got on my RedHat
+ * Linux 10 box a segmentation fault from js after setting the stack limit
+ * to 100K. When I set the stack limit to 20K I still got the segmentation fault.
+ * Only after -s was changed to 15K, too-deep recursion was detected:
+ *
+
+ ~/w/js/x> ulimit -s
+ 100
+ ~/w/js/x> js  fintest.js
+ Segmentation fault
+ ~/w/js/x> js -S $((20*1024)) fintest.js
+ Segmentation fault
+ ~/w/js/x> js -S $((15*1024)) fintest.js
+ fintest.js:19: InternalError: too much recursion
+
+ *
+ * After playing with numbers it seems that while processing try/finally the
+ * recursion in js_Emit takes 10 times more space the corresponding recursion
+ * in the parser."
+ *
+ *
+ * Note the use of the new -S option to the JS shell to limit stack size.
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=225061. This in turn
+ * can be passed to the JS shell by the test driver's -o option, as in:
+ *
+ * perl jsDriver.pl -e smdebug -fTEST.html -o "-S 100" -l js1_5/Regress
