#### reducing command-line just make the segfault less likely, but still possible, eg using:
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.7.3/collect2 -dynamic-linker /lib64/ld-linux-x86-64.so.2 -o test-http-response-parser /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64/crt1.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64/crti.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/crtbegin.o -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3 -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../x86_64-pc-linux-gnu/lib -L/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../.. test-http-response-parser.o .libs/http-date.o .libs/http-parser.o .libs/http-header.o .libs/http-header-parser.o .libs/http-transfer-chunked.o .libs/http-message-parser.o .libs/http-response-parser.o ../lib-test/.libs/libtest.a ../lib/.libs/liblib.a -ldl -lrt -lgcc -lgcc_s -lc /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/crtend.o /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.3/../../../../lib64/crtn.o

(no  --eh-frame-hdr -m elf_x86_64, (no-)as-needed, ...) divides by 3 or 4 the probability of the segfault)
