I think valgrind shows the problem is in deparse.c:
245 strncpy(data, CHAR(STRING_ELT(svec, 0)), 10);
246 if (strlen(CHAR(STRING_ELT(svec, 0))) > 10) strcat(data, "...");
You need to put a '\0' into data[10] after that strncpy
so strcat can find the end of the string when the length
of the copied string is >=10. It currently runs into
uninitialized memory at the end of ".Primitive".
