The backtrace would not very useful, as you don't have the debug symbols 
available. Please install the debug packages for the libraries listed by gdb, 
most likely something like pcre-debug and libc-debug. Then run gdb again, this 
time it should not say "no debugging symbols found", at the gdb prompt, type 
'bt full' and then send the output.
