  • Ticket #1337 – Description

    initial v1  
    1 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.

    33I 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.

    55The output when crashing is this:
    66
     7{{{
    78    test: runtime.c:2797: C_save_and_reclaim: Assertion `av > C_temporary_stack_bottom || av < C_temporary_stack_limit' failed.

    1519I'll attach my test code, which depends on bind (egg) and glib.
