Runtime error: 'allocation node size exceeds supported maximum of allocator'

[rushipatel]

When I run my cross-compiled fastrtps application on the aarch64 linux platform, I see following exception

[foonathan::memory] Allocator foonathan::memory::memory_pool (at 0x559f6319a8) received invalid size/alignment 56, max supported is 48terminate called after throwing an instance of 'foonathan::memory::bad_node_size'
  what():  allocation node size exceeds supported maximum of allocator
Aborted

I have used file container_node_sizes_impl.hpp generated by nodesize_dbg on target platform. The output of the nodesize_dbg from target platform is as following

How are you creating the pool and what do you allocate with it?

[rushipatel]

It looks like an issue from the application side. I'm working on debugging it and will provide more info as I find. I'll leave the issue closed for now.

[rushipatel]

The -DFOONATHAN_MEMORY_CONTAINER_NODE_SIZES_IMPL is only applicable to QNX platform and so passing this flag was not effective. The node size info was not used by memory and caused FastDDS to use custom node size implementation. The segfault occurs at line 230 of RTPSReader.cpp for the map<GUID_t, uint16_t> object.

The fix was simple, manually copy container_node_sizes_impl.hpp to src/ under the build directory.

[foonathan]

Wait, so what container_node_sizes_impl.hpp was used?

I encountered the same problem, how can I solve it？

[jiangkunkun1993]

hello ,when i run ./HelloWorldExample subscriber && ./HelloWorldExample publisher
i encounter the error . i use cross compile ,then place the binary HelloWorldExample on ARM.

can you tell me how to fix it .

This is an issue with Fast-DDS, which will be resolved by the referenced PR.

[stewy-lewy-TR]

Has there been any resolution on this issue? Which version of foonthan memory should be used with the latest release of Fast-DDS?

[MiguelCompany]

@stewy-lewy-TR The latest release of Fast-DDS is nightly tested with release v0.7-1 of this repo.
