C fasta is broken

[italomaia]

fasta implementation for C is broken; "Segmentation fault"

[italomaia]

Seems related to this call:

generate_And_Wrap_Pseudorandom_DNA_Sequence(iub_Nucleotides_Information,
		sizeof(iub_Nucleotides_Information) / sizeof(nucleotide_info), 3 * n);

[99991]

Compiling and running with address sanitizer does not raise any issues:

gcc -g -fsanitize=address -fsanitize=undefined -pipe -Wall -O3 -fomit-frame-pointer -march=native -std=c99 -mfpmath=sse -msse3 -fopenmp fasta.gcc-2.c -o fasta.gcc-2.gcc_run && ./fasta.gcc-2.gcc_run 25000000 > /dev/null

Valgrind does not find any issues either. But on the first attempt, I tried to run the program without a parameter and it segfaulted here:

Energy-Languages/C/fasta/fasta.gcc-2.c

Line 311 in 1356528

const intnative_t n = atoi(argv[1]);

Was that perhaps the issue for you as well?
