 Priority:  major     |             Milestone:  4.13.0
Component:  compiler  |               Version:  4.12.0
 Keywords:            |  Estimated difficulty:  medium
----------------------+-------------------------------
 `take_profile_sample`, which is called from within a signal handler, uses
 `malloc` to allocate new bins for its hash table.
 Doing so is frowned upon as the signal may be processed while the runtime
 owns the global malloc lock leading to an awful deadlock.

 I can confirm that I've been able to do a profiled run by replacing the
 malloc with a simple arena allocator.
