I am attempting to use tesseract's API in my project and everything works
as expected on ubuntu when running the code, but I am receiving a seg fault
when I moved everything over to an alpine docker container.
The backtrace from the segfault:

I first tried installing the tesseract-git package in alpine where I
noticed the issue so I just finished compiling the master branch of
tesseract-ocr and I am still receiving the seg fault.
Also my compiled version of tesseract runs fine through the CLI.
I am lost as to what else could be the problem and would appreciate any
help/direction on how to solve this issue.
