Error: LD: symbol not found: '__data_start'

when running test application I encounter a new problem of dynamic linker

[init -> test-go] 0x1000000 .. 0x10ffffff: linker area [init -> test-go] Error: LD: symbol not found: '__data_start' [init -> test-go] Error: Uncaught exception of type 'Linker::Not_found'

any ideas how to fix?

seems that main binary test-go do have a weak ref to this symbol as nm show: w __data_start in some places of new code appeared after 10.3 gcc I found extern const char __data_start[] __attribute__ ((weak));

where I can add it, in what ld script?

Sincerely, Alexander
