I spent so much time trying to reliably reproduce the error that I didn't think to take that step once I had. The output looks like this: Set-Cookie: asdf=a%253A11%253A%257Bi%253A0%253Bs%253A2%253A%252211%2522%253Bi%25 3A22%253Bi%253A1%253Bi%253A17%253Bi%253A1%253Bi%253A20%253Bi%253A1%253Bi%253A24% 253Bi%253A1%253Bi%253A26%253Bi%253A1%253Bi%253A25%253Bi%253A1%253Bi%253A23%253Bi %253A1%253Bi%253A21%253Bi%253A1%253Bi%253A19%253Bi%253A1%253Bi%253A16%253Bi%253A 1%253B%257D Segmentation fault (core dumped) So it's actually sending the cookie, but crashing before returning from setcookie(). But why is it so sensitive the the name and contents of the cookie? I know just barely enough about gdb to get a backtrace, as follows: #0 0x400b73c2 in ?? () from /lib/libc.so.6 #1 0x4010f3fc in ??
