Hi Epic,
we have one rather frequent outstanding crash in the shipped game (5.4.4 + RHI Parallel Translate).
We can’t t get a repro locally from our QA, we only see a lot of dumps from out in the wild.
I pasted the callback. The error is 0xC0000005: Access violation reading location 0x0000000000000038
In the Shipping minidumps, everything is heavily inlined, there isn’t much to see and judging from the 0x38 offset, we’re accessing a null pointer. But I can’t see which member it might be.
I see in CL34146199, which was just after 5.4 and after the RHI Parallel Translate merge (which we got), that you removed/postponed the whole call to ConvertToExternalUniformBuffer which we’re crashing in. Could it potentially help? We have raytracing disabled.
Although, I fear it will be an out of memory situation, out of bounds, or a lifetime issue.
Thanks for any ideas, Pavel
aaaa
