I'm having an issue where HAProxy is crashing with no explanation when I switch from 1.4.12 to 1.5-dev12. The reason I'm switching is for the SSL offloading.

My config file doesn't have any errors, it's quite simple and it works well with 1.4 - but for some reason when I run it with 1.5-dev12 I see the logs noting that the two backends I have have been set up, and then when I hit one of the frontends, I get an HTTP 400 in the browser and suddenly HAProxy isn't running anymore when I check.

I understand that a common workaround to the lack of SSL support for HAProxy is to use Stud, and I may go with that since I am in need of an SSL solution for my service, but before I dele into that world I thought I might see if anybody has experienced the same problems and might know how to fix it.

The server is Ubuntu 10.04 and I followed the make instructions on the Exceliance blog here.

EDIT: On the advice of Kyle Brandt, I did a bit more investigation. I attached gdb to the haproxy process and when the crash occurred this is what I got:

Program received signal SIGSEGV, Segmentation fault.
0x0804e5c2 in dequeue_all_listeners (list=0x9e1a418) at src/protocols.c:184
184     list_for_each_entry_safe(listener, l_back, list, wait_queue) {

P.S. HAProxy is awesome, so thank you Exceliance for providing us with something so useful :)
