Bug#1042009: onetbb: FTBFS on armel: error: ‘void __atomic_store_1(volatile void*, unsigned char, int)’ writing 1 byte into a region of size 0 overflows the destination [-Werror=stringop-overflow=]

I managed to reduce it to this patch, now applied to git as 1050-armel-atomic-past-buffer.patch. No idea why it help, but worked when doing test build on armel / abel.debian.org. --- tbb.orig/src/tbb/concurrent_monitor.h 2023-07-30 20:28:22.251868539 + +++ tbb/src/tbb/concurrent_moni

I suspect this trigger a compiler bug on armel, as the code seem just fine with me. I have tested on armel and managed to get the code building with the following patch. diff --git a/src/tbb/concurrent_monitor.h b/src/tbb/concurrent_monitor.h index 3d20ef5b..b010b2e5 100644 --- a/src/tbb/concurre
