crash test case
Hello,
I'm currently developing a new fuzzing feature, and I found a crash in objdump.
I downloaded from git master, and I built it with Ubuntu 16.04 with gcc 5.4.0
with ASAN, and the following command to build objdump from the source:
CFLAGS="-O1 -fsanitize=address -U_FORTIFY_SOURCE" ./configure; make clean all;
You can reproduce the crash with the following command:
./objdump -d <attached file>
The AddressSanitizer message of the crash is:
==12140==AddressSanitizer CHECK failed:
../../../../src/libsanitizer/sanitizer_common/sanitizer_posix.cc:121 "(("unable
to mmap" && 0)) != (0)" (0x0, 0x0)
