Michael Tro?\195?\159 writes:
gen_wctype segfaults on my system when optimized with -O2. It does work 
without optimization, even -O1 does not cause the segfault.  Problem is in 
newopt, at gen_wctype.c:865:
	memcpy(tbl->ti + i * blocksize, ti[uniqblock[i]], blocksize);

The segfault is caused by the uninitialized variable uniqblock when
newopt is called recursively.  The attached patch fixes this.
