Description of problem: 
bash segfaults with very long commandline. 
Seems to need some special characters in the commandline, doesn't  
happen with normal text. 
Version-Release number of selected component (if applicable): 
How reproducible: 
Steps to Reproduce (Don't ask why I did this): 
1. open bugzilla's query page 
2. mark every product/version/component/status/resolution 
3. press search 
4. abort search (it won't complete anyway) 
5. mark URL and paste it into bash (its insanely long) 
Actual results: 
bash aborts with segfault: 
free(): invalid pointer 0x8224600! 
Program received signal SIGSEGV, Segmentation fault. 
0x006a277d in malloc_consolidate () from /lib/tls/libc.so.6 
(gdb) bt 
#0  0x006a277d in malloc_consolidate () from /lib/tls/libc.so.6 
#1  0x006a1d5a in _int_malloc () from /lib/tls/libc.so.6 
#2  0x006a110d in malloc () from /lib/tls/libc.so.6 
#3  0x08091517 in xmalloc () 
#4  0x080a4291 in readline_internal_teardown () 
#5  0x080a4588 in readline_internal_char () 
#6  0x08083480 in termination_unwind_protect () 
Expected results: 
Additional info: 
probably a readline problem
