'Segmentation fault after main returns when building for coverage with gcc

I have a C program which compiles and executes fine when I build it without instrumentation flags. However, when I add instrumentation flags (-fprofile-arcs -ftest-coverage) the same program crashes with a segmentation fault after my main function returns

Has anyone seen this before when building for gcov?

I can see the following stack trace when debugging with gdb in vscode

c gcc gcov

Solution 1:^[1]

This turned out to be a write beyond array bounds in my program, which was eventually causing segfault later on in the execution
