[Gnash-commit] [bug #37223] JavaScript call didn't reach the ExternalInterface callback

[Nutchanon Wetchasit]

Follow-up Comment #10, bug #37223 (project gnash):

Running original js2flash test case (not js2flash-rootcb) on current Gnash
git
(using either fake host container configuration, or running `js2flash.html`
via browser) would now cause it to crash:

A debugging session is active.

        Inferior 1 [process 20048] will be killed.

Quit anyway? (y or n) y



I suspect that GC-related part of previous patches is the culprit.
