A piece of C code was written to run normally in the main function, passing a thread-related function to pthread_create. It ran successfully on an x86 platform, but failed on an embedded board. The code includes various header files and functions from different libraries, including stdio, stdlib, unistd, and others. There are multiple variables declared and functions called, including printf, strcpy, and pthread_create. The issue could be related to the specific environment or platform being used, or it could be due to a bug in the code itself. Further investigation and error analysis are needed to determine the root cause of the problem.
