static int bar[];

void main () {
    import std.concurrency : spawn;
    spawn ( & foo );
}

void foo () {
    bar ~= 0;
}

This program segfaults if compiled with -profile=gc. Seems to happen at rt_term of runAll at dmain2.d.

Profiler fails with atomic operations:

import core.atomic;

shared struct S
{
    uint counter;

    bool inc() shared
    {
        atomicOp!("+=")(counter, 1);
        return true;
    }
}

int main(string[] argv)
{
    S s;

    return 0;
}

This program segfaults if compiled with profiler hooks

After an update from 2.071.2 to 2.072.0 a seg fault with the profile option on a mac appear with the following example

void main() {}
void f()
{
    import core.atomic: atomicOp;
    shared size_t workUnitIndex;
    atomicOp!"+="(workUnitIndex, 1);
}

which does not appear with the prior version of atomic.d

Many thanks to ag0aep6g for helping with the code.
