I don't think you can blame Org for the crashes you've experienced. Org
exports the string "a_variable_deleteThisAndItWorks" to
"a\(_{\text{variable}}_{\text{deleteThisAndItWorks}}\)" which is not a
valid LaTeX expression. This invalid output is not the fault of Org, it
is the fault of the input string. Since there are different ways of
interpreting "a_variable_deleteThisAndItWorks," you have to tell Org
which interpretation you want it to make when you export to LaTeX. This
means additional markup of the string is required.
That the exported LaTeX file crashes your installation of pdfTeX (or
whatever TeX engine you use) when you process it is not the fault of
Org. The exported LaTeX file contains an invalid LaTeX expression that
came from a ambiguous string, so pdfTeX shows an error when processing
the LaTeX file. Using additional markup of the string so that Org
exports it as a valid LaTeX expression is the solution to the problem.
