EXC_BAD_ACCESS when trying to get key type before any access about credis HOT 6 CLOSED

The EXC_BAD_ACCESS is from xcode. I get a segmentation fault when running in 
terminal.

I haven't been able to try this myself but do you think it is a problem in 
Credis? 
Could be something in the Redis server, have you tried with other client libs 
if the 
same error is returned?

Hi romfelt,

I just tried it with Ezra's  ruby library. I was able to successfully query a 
key's type like so:

require 'redis'
r = Redis.new
r.type 'mykey'
=> "string"

So yes, unfortunately I think it's a problem with credis. I am trying to debug 
it now, but I'm not that much of a 
C guru.

It seems like the problem stems from like #778:

char *t = rhnd->reply.bulk;

*t is coming back null. Hope this helps some. I'll continue to try my luck at 
debugging it, but I really doubt I 
can. Thanks for all your work on credis!

One other note of interest: whenever I use the credis_type() function, it is 
altering the value of the previous key.

For example:

This returns the value just fine, as expected:.

char *val;
credis_get(rh, "mykey", &val);
printf("mykey: %s", val);

However, this will alter mykey's value:

char *val;
credis_get(rh, "mykey", &val);
type = credis_type(rh, "mykey");
printf("value: %s -- type: %s", val, type);

Hope this helps some...

This issue was closed by revision r28.

found a bug. used reply bulk instead of reply line. this resulted in 
segmentation fault 
when credis_type() was the first function used since reply bulk was 
uninitialized and 
by mistakingly used.
