Hey ho.

I'm struggling hard with a backlog of curl mails. Here's one of the reports
I've got. Feel free to investigate, comment, suggest. Whatever.

(I removed Vladi's email address below since he mailed me this privately)

Subject: the curl bug
hi!
  You remember I contacted you once before about a rare (strange) bug
  in curl. Now I think I found the exact situation which triggers it.
  Unfortunately I couldnt make it to debug it myself -- gdb says it
  cannot set/find _Transfer() breakpoint and some weird messages :)
  I removed -O2 but it didn't help... however this is it:
  I take 3 text files:
  -rw-r--r--   1 cade     users      100000 Sep 21 14:36 l01.txt
  -rw-r--r--   1 cade     users        5000 Sep 21 14:36 l02.txt
  -rw-r--r--   1 cade     users        2000 Sep 21 14:37 l03.txt
  I put them in my public_html on the local machine:
  /home/cade/public_html/l*.txt
  Then start curl:
  curl -O http://localhost/~cade/l[01-03].txt
  First file is downloaded ok, second starts (i.e. curl just reports
  0% downloaded stats) and it segfaults right there! AFAI can find the
  situation is that _Transfer( conn* ) gets NULL and in speedcheck( data*)
  somewhere around line 500 or something data* gets random value
  sometimes it is NULL other some invalid address (0x1 etc...)
  It never gets to the third file...
  I can reproduce this error clearly with latest stable version:
  curl 7.2 (i586-pc-linux-gnu) libcurl 7.2.1
  and with 6.5.2
  I think it is important that second file is smaller that first one
  and that first one is about 100K, I mean that with files with sizes
  of 4K and 1K (for example) the bug don't happen! I couldn't reproduce
  it neither with equally sized files nor in reverse order i.e. smaller
  first.
  I hope this will finally (and hopefully) help to fix this bug!
  
  If you still cannot reproduce it (which I really don't believe), I 
  can send you my curl sources l*.txt files and anything you think
  can help...
  Thanx for the attention and good luck!
P! Vladi.
