Aborting application. Reason: Fatal log at [xxx/bcov/src/graph/DominatorTree.cpp:210]

Hi,

Here is a crash I have encountered during the binary analysis using bcov. The binary test2 is compiled with gcc -w -O1 -fno-inline test.c -o test2 and the compiler version is gcc version 13.0.0 20220528 (experimental) (GCC).

$bcov -m dump -f "func_1" -i test2
Aborted (core dumped)

$cat bcov.log
I | call graph built successfully

W | Aborting application. Reason: Fatal log at [/home/haoxin/disk-dut/research/github/bcov/packages/bcov/src/graph/DominatorTree.cpp:210]

Here is the binary I used:
test2.zip

Thanks!
