maybe i shall add something detail, the envroment is cross-compiler build， not gcc, is there any solution?

There are memory-related errors before it crashes:

2024-08-26 08:02:29.577 WARN  [23902] [rtc::impl::ThreadPool::schedule@105] Unable to allocate structure for ECDSA P-256 key pair

It looks like either the build is broken or the program is indeed out of memory (which might not be handled correctly by plog in this case).

thank you, but i haven't change any code of libdatahanel，do you have any ideas about how to fix it?

paullouisageneau commented 2 weeks ago

It is not related to a code change, it looks like an issue with OpenSSL. The prime256v1 curve might have been disabled during OpenSSL build. However I don't really understand how it would lead to the crash.
