Hello,

I recently wrote a program using libcurl that starts up a bunch of threads
(default: 16) and has each thread repeatedly get files from an FTP server
and web server (IIS). The program currently runs on Debian linux with
kernel 2.4.18. libcurl version is 7.9.7 (latest). Program seg faults after
a certain amount of time (very fast if the files are small but takes longer
for larger files; small files make connections rapidly etc.). Here is a
backtrace:

Program received signal SIGSEGV, Segmentation fault.
