Hi,
I've compiled 1.5-dev20 on debian wheezy and now I get a double free
or
corruption bug. Haproxy will not start.
Interesting, I never experienced this one. Could you please run it
through
gdb and issue "bt full" ?
Otherwise if you can send me privately the config you use to reproduce
this, without sensitive information, it would be great!
Hmmm, I think something is not right here. I do have debugging symbols
in the binary but I get nothing AFAICS. Am I doing something wrong here?
Or is the SIGABRT the problem?
I'll send you my config.
