Summary: Test 253 and 255 segfaults with curl-7.15.1

Initial Comment:
Since these 2 tests failed with the previous version of
Curl too (7.15.0) I 'll submit a bug report - Using the
search I could only find similar bugs from 2000-2003.

Thanks, now we're getting closer.

What I really want to see is frame #0 and what the exact
reason for the segfault is in that function. The function
itself doesn't do much so I'm very puzzled.

It is weird that you didn't get any proper debug info for
that file. Can you do a make clean and rebuild and see if
you can get info for frame #0 too?

You might consider configure --disable-shared and
--enable-debug too to get an even smoother debuggable
version built.

Thanks for your help!

I haven't played around with gdb a lot so if I did something
wrong let me know.

(I mailed you the following as well since you submitted this
report anonymously)

Can you rebuild curl staticly and run the single tests with
-g [num]? Like:

 $ cd tests
 $ ./runtests.pl -g 253

... as then it'll fire up gdb for you, and when you enter
'run' it'll hopefully
catch the segfault nice and clean and you can show us a
stack trace and
hopefully contents of some local variables in a suitable
place in the trace.

What glibc version are you using?
