I can reproduce the segfault only with a 32-bit ABI.
read(3, "-e \n\r\n\r# this is a comment line "..., 4096) = 54
mmap2(NULL, 224735232, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0xea604000
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0xca604012} ---
If I understand correctly, the read system call comes from the initial
fread() to get the size, and the mmap2 comes from the allocation.
