Re: [Pharo-project] Headless image hanging

And the assert is failing is indeed in sqExternalSemaphores.c

Here:

/* Signal the external semaphore with the given index. Answer non-zero on
* success, zero otherwise. This function is (should be) thread-safe;
* multiple threads may attempt to signal the same semaphore without error.
* An index of zero should be and is silently ignored.
*/
sqInt
signalSemaphoreWithIndex(sqInt index)
{
    int i = index - 1;
    int v;

    /* An index of zero should be and is silently ignored. */
    assert(index >= 0 && index <= numSignalRequests);

    if ((unsigned)i >= numSignalRequests)
        return 0;

BTW...your VM is quite "old". Why don't you give a try with a new one?

Bernat,

You could try to use the Finder to search the source(s) for this string or parts of it.
I couldn't find it in my image…

That's an assert that is failing in the VM side.

index >= 0 && index <= numSignalRequests 133

means that "index >= 0 && index <= numSignalRequests" evaluated to false, and 133 is the line number in the C code.

BTW, is not this the problem of Sempahores or I don't know what that you need to change/make bigger in Cog ?
