Why is it dividing by 32? Another case of premature optimization? If you replace that with: covb = (unsigned *)calloc(numlines, sizeof(*covb)); Then it works fine. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=9466 Created an attachment (id=1184) More reduced test case If move the code line `int dummy = 0;` in cb.i from line 161 to 160, segfault disappeared. The line number depends on minimum allocation size of calloc(). As far as I see, currently it allocates at least 20 bytes (20 * 8 == 160 bit). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Why is it dividing by 32? Another case of premature optimization?covb is a bit vector, it must have numlines bits in it. Since unsigned's are 32 bits wide, it rounds it up to the number of 32 bit unsigned's to allocate. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
