crash test case
Hello,
I'm currently developing a new fuzzing feature, and I found a crash in nm.
It crashed in vms_traverse_index at vms-lib.c:230
I built it with Ubuntu 16.04 with gcc 5.4.0, and the following command to build
nm from the source:
./configure --enable-targets=all ; make clean all -j 4; make install
You can reproduce the crash with the following command:
./nm <attached file>
The call stack of the crash is:
Program received signal SIGSEGV, Segmentation fault.
