[Speedycgi-users] speedy bus error under FreeBSD-5.x

[Lars T. <la...@th...>]

Hi all,

It seems the speedy executable has some problems running under FreeBSD-5.x,
e.g.:

--cut--
[lth@bhor speedy]$ ./speedy -- -v
Bus error (core dumped)
[lth@bhor speedy]$
--cut--

This, and another bus error problem stems from a couple of code bugs, solved
by the following patch:

Apparently, malloc() of current beta versions of 5.x has the the 'J' flag
set, and is therefore much more unforgiving regarding pointer overruns than
under 4.x (and under Linux), so this is probably why this has not been
discovered before.

Thanks to tobez for invaluable help with debugging this.
