When running btest, it gets this:

ERROR: Test floatPower2 failed.
  Timed out after 10 secs (probably infinite loop) 

When compiling btest, it gets some warning, but the tests other than floatPower2 works well.

Warning as bellow:

$ make btest
gcc -O -Wall -m32 -lm -o btest bits.c btest.c decl.c tests.c
btest.c: In function ‘test_function’:
btest.c:334:23: warning: ‘arg_test_range’ may be used uninitialized [-Wmaybe-uninitialized]
  334 |     if (arg_test_range[2] < 1)
      |         ~~~~~~~~~~~~~~^~~
btest.c:299:9: note: ‘arg_test_range’ declared here
  299 |     int arg_test_range[3]; /* test range for each argument */
      |         ^~~~~~~~~~~~~~

I don’t know why it gets timed out.Is this warning the cause?

I expected the program to test if my code is correct.
