On GCC 15 the following warnings is emitted:

nolibc-test.c: In function ‘run_stdlib’: nolibc-test.c:1416:32: warning: initializer-string for array of ‘char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (11 chars into 10 available) [-Wunterminated-string-initialization] 1416 | char buf[10] = "test123456"; | ^~~~~~~~~~~~

Increase the size of buf to avoid the warning.

It would also be possible to use __attribute__((nonstring)) but that would require some ifdeffery to work with older compilers.
