#4 0x080621ff in main ()
After this, I've checked the libapr1 bugs and found there are three
bugs reported about it: #392049, #392373 and #392646
It seems that the problem is related to libapr1 when using a 2.4
kernel, so maybe this bug should be reassigned to libapr1 and merged
with those three.
Thanks for your help.
