Compilation Error Fedora

[acronymhaterheidi]

I have encountered a compilation error that I have not seen before on a new Fedora installation. Here are my system details:
Fedora 30
gcc 9.1.1
openssl 1.1.1b FIPS
curl 7.64.0

Here is the output of make:
cc -Werror -Wextra -Wall -pedantic -fPIC -O2 -std=gnu99 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -fstack-protector-strong -fwrapv --param ssp-buffer-size=4 -fvisibility=hidden -fPIE -Wno-missing-field-initializers -Wno-gnu-zero-variadic-macro-arguments -Ilib -Iapps -c -o lib/acvp_paging.o lib/acvp_paging.c

I googled around a little but I didn't find anything useful. If you have any idea what might be causing this that would be wonderful.

Thanks,

This is a common error when you have a static buffer and the strncpy has the potential to exeed the buffer without a terminating \0. Thus, the solution is simple: strncpy(parametrized_url, url, sizeof(parametrized_url) - 1); /* Safety measure */ parametrized_url[FILENAME_MAX - 1] = '\0';
