Subject: [linus:master] [perf dsos]  7a9418cf7f: util/dsos.c:184:8: runtime
 error: null pointer passed as argument 2, which is declared to never be null



Hello,

kernel test robot noticed "util/dsos.c:184:8: runtime error: null pointer passed as argument 2, which is declared to never be null" on:

commit: 7a9418cf7f05a74cbc9d4c750ee1bfddaa11f121 ("perf dsos: Switch hand crafted code to bsearch()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

[test failed on linus/master      a3e18a540541325a8c8848171f71e0d45ad30b2c]
[test failed on linux-next/master 6906a84c482f098d31486df8dc98cead21cce2d0]



the issue can be reproduced by below commands:

$ sudo make WERROR=0 ARCH= DEBUG=1 EXTRA_CFLAGS='-fno-omit-frame-pointer -fsanitize=undefined -fsanitize=address'
$ sudo ./perf record  -e 'cpu/branch-instructions/' -- sleep 1
util/dsos.c:184:8: runtime error: null pointer passed as argument 2, which is declared to never be null



If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
| Closes: https://lore.kernel.org/oe-lkp/202406180932.84be448c-oliver.sang@intel.com
