This sounds like the typical case that happens if you inadvertently write the name of a macro ("function") that gets expanded. Like this:

AC_DEFUN([TEST_FOO],
[
   echo Debug: we are running in TEST_FOO
])


will fail to compile with a stack overflow, since the `TEST_FOO` in the debug output will be recursively expanded with the function we're trying to expand. (Been there, done that, has produced profanities over autoconf enough to guarantee me a very hot place in the afterlife, before I figured that one out...)

So check if you are trying to write a "keyword" where a substring matches some other defined macro.
