This is strange, I cannot see what is wrong with the code:
https://github.com/yast/yast-core/blob/58b154edb1a8a755ca957a1155e2bd3f49243505/liby2/src/Y2ProgramComponent.cc#L402

397 char *v = NULL;
398
399 if (is_non_y2)  v = strdup(value.c_str());   // no brackets
400 else            v = strdup(("(" + value + ")").c_str());
401
402 bool error = (write(to_external[1], v, strlen(v)) < 0);
