[Qt-interest] Demo Browser Core Dump

[Enrico Ros]

1. You may need to issue "ulimit -c unlimited" before launching your 
executable. That removes any size limit for core dumps.

2. Also look at "/proc/sys/kernel/core_pattern" if you have a recent kernel to 
see where the core dump will be generated. Moving it to a remote directory may 
help you save disk space if this is the problem. You can do this with "echo 
/tmp/mounted/core > /proc/sys/kernel/core_pattern")

3. Finally your systems couldn't have enough memory for being able to generate 
a core dump. Enable virtual memory on a swap file and you're ok to go (dd 
if=/dev/zero of=/tmp/SWAP bs=1024 count=524288; mkswap /tmp/SWAP; swapon 
/tmp/SWAP)

Ciao,
Enrico
