Hi,

I keep running into trouble with using curl_easy_getinfo:
I'm using the same CURL handle for multiple connections. Before
every new connection request, I reset the handle using
curl_easy_reset. Afterwards, I set the options for the handle
using curl_easy_setopt (CURLOPT_URL, CURLOPT_FOLLOWLOCATION to
1, CURLOPT_WRITEFUNCTION, CURLOPT_WRITEDATA,
CURLOPT_ERRORBUFFER) and call curl_easy_perform. So far, this
works fine. But when I call curl_easy_getinfo on the handle
after having fetched the site to get the effective URL, I still
works for the FIRST connection. However, on the next connection
using the same handle, the program receives segmentation fault
while performing curl_easy_perform. The following backtrace from
gdb shows what's going on (or does it?):

#0 0x00007ffff740d933 in malloc_consolidate () from
/lib64/libc.so.6
#1 0x00007ffff740f655 in _int_malloc () from /lib64/libc.so.6

#11 0x00000000004020b6 in main (argc=2, argv=0x7fffffffe078) at
main.c:209

(Don't get confused by url.c in #10, this is from my own source
code, it's not the url.c from libcurl).

Where is my mistake? How is libcurl (curl_easy_getinfo) used
correctly?

Thanks and regards
Till
