Comment (by anevilyak):
Is the crash consistently in the same location? At a glance, the backtrace
indicates possible heap corruption, where the crashing code is more
typically the victim, and as such not so helpful at tracking down the
cause. It'd be potentially interesting to see the resulting crash report
if Debugger is started with {{{ LD_PRELOAD=libroot_debug.so }}}.
Otherwise, I also note that your VM is getting relatively near to using
all of its memory, with >1GB of heap in the Debugger team itself, so it
may simply be running out of memory, which isn't necessarily handled
gracefully everywhere in the system libraries. As such, it'd also be
interesting to know if increasing the amount of memory given to the VM
makes a difference.
On the other hand, another possibility is address space exhaustion, as
would occur when trying to debug e.g. WebKit on a 32-bit system (it's
difficult to tell for certain from the given information). If that one's
the case, then the only real solution would be to use a 64-bit build.
