Hm, nobody has reported this before.

Memory allocation failure is fatal by necessity. Consider that WebKit depends on GLib, and g_malloc() crashes the application on allocation failure. (GLib's g_malloc() just wraps glibc's malloc with a check to see if allocation failed, and a crash if so.) So no library or application that uses GLib can avoid crash on allocation failure.

I suppose it could be more likely to occur with bmalloc if bmalloc allocations memory in larger chunks than glibc does. If the difference is significant enough to encourage you to disable bmalloc, that would certainly be worth a separate bug report.
