Tom Lane eaf99e4c4a Ensure Soundex difference() function handles empty input sanely. ... fuzzystrmatch's difference() function assumes that _soundex() always initializes its output buffer fully. This was not so for the case of a string containing no alphabetic characters, resulting in unstable output and Valgrind complaints. Fix by using memset() to fill the whole buffer in the early-exit case. Also make some cosmetic improvements (I didn't care for the random switches between "instr[0]" and "*instr" notation). Report and diagnosis by Alexander Lakhin (bug #17935). Back-patch to all supported branches. Discussion: https://postgr.es/m/17935-b99316aa79c18513@postgresql.org		2023-05-16 10:53:42 -04:00
