 Priority:  major     |             Milestone:  someday
Component:  unknown   |               Version:  4.11.0

----------------------+--------------------------------
 Running scheme code from a foreign-lambda called using a glib callback can
 make the runtime crash. The bug is not easy to reproduce, since every
 small change to the code can make it easier or harder to trigger.

 I have been able to trigger it only when doing a significant amount of
 work on the callback, but taking more time to return doesn't necessarily
 make it easier to trigger, and sometimes multiple calls are needed.

 The output when crashing is this:

     test: runtime.c:2797: C_save_and_reclaim: Assertion `av >
 C_temporary_stack_bottom || av < C_temporary_stack_limit' failed.

 I'm running this on the following release (installed from the Arch Linux
 repos):

     Version 4.11.0 (rev ce980c4)
     linux-unix-gnu-x86-64 [ 64bit manyargs dload ptables ]
     compiled 2016-05-28 on yves.more-magic.net (Linux)

 I'll attach my test code, which depends on bind (egg) and glib.
