The crash was the result of passing a null pointer to strlen when allocating memory for the PID file:
/* we can theoretically live without a config file */
home = getenv("HOME");
if (home) {
config.file = calloc(1, strlen(home) + 9);
sprintf(config.file, "%s/.wmixrc", home);
}
/* handle writing PID file, silently ignore if we can't do it */
pid = calloc(1, strlen(home) + 10);
sprintf(pid, "%s/.wmix.pid", home);
fp = fopen(pid, "w");
if (fp) {
fprintf(fp, "%d\n", getpid());
fclose(fp);
}
free(pid);
This was fixed in a later release, 3.3, which has since packaged and
uploaded to the archive:
