Hi friends,

i have checked the gmp-4.2.4 source with a static code analyis tool (cppcheck). It brought up an issue in file /mpz/export.c at line 66.

I used the following command:
cppcheck -q -a -j2 -f gmp-4.2.4/
[./mpz/export.c:66]: (error) Wrong assignement of an auto-variable to an effective parameter of a function

The code, the code analysis tool complains about:
  if (countp == NULL)
    countp = &dummy;

Best regards

Ettl Martin
