Michael Troß 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.
