Hello,

We are currently working on fuzz testing feature, and we found a failed to allocate error on tiffinfo.

The stack traces are as follow:

Step to reproduce

We configured tiffinfo using CFLAGS="-g -O0 -fsanitize=address" CXXFLAGS="-g -O0 -fsanitize=address" ./configure --prefix=$(pwd)/ and build it using make -j10, and run it with:

./tiffinfo -D libtiff -i tiffinfo -s <attached file> -d -j
