[C++] arrow-io-memory-benchmark crashes

"arrow-io-memory-benchmark" SIGSEGV in latest code base. It worked at least when my last commit 8 days ago: b1d4c86eb28267525c52f436c3a096e70b8ef6e0

Tested on x86 host. Build with "cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DARROW_COMPUTE=ON -DARROW_BUILD_BENCHMARKS=ON .."

stack backtrace attached
