Qt Creator >= 3.x segfaults at startup on Linux/ia64 (JS engine related?)

Hi,

With Qt Creator 3.x and above, it's simply impossible to start up Qt Creator (instant crash when clicking the Qt Creator icon from desktop environment or starting from the command-line). Last working version was Qt Creator 2.8.1, with Qt 4.8.6 at the time.

From the attached backtraces (for Qt Creator 3.6.1 and 4.0.3), it seems to relate to JS engine. Is it new that Qt Creator now requires JS to work? In this case, I fear that Qt Creator won't work anytime soon on Linux/ia64, as the only working JS implementation there is Mozilla's Spidermonkey (see [1] for WebKit situation).

If this crash doesn't come from JS engine in the end, well, let me know how I can help further

Émeric
