In linuxfromscratch we normally build grep without pcre using:
./configure --prefix=/usr --bindir=/bin
make
It works fine.
Later after pcre is installed users can rebuild grep with exactly the
same instructions, but with grep-3.4, I get a segfault with
grep --help
and all other command line entries. Adding --disable-perl-regexp
restores grep but of course removes pcre regex capabilities.
I went back and built grep-3.3 with pcre and everything worked with the
same pcre library as above.
I did some preliminary gdb testing and got:
Reading symbols from src/grep...
(gdb) run --help
Starting program: /build/grep/grep-3.4/src/grep --help
Program received signal SIGSEGV, Segmentation fault.
0x000000000041cc03 in __libc_start_main ()
(gdb) bt
#0 0x000000000041cc03 in __libc_start_main ()
#1 0x000000000040715a in _start () at ../sysdeps/x86_64/start.S:120
We are using glibc-2.31 and gcc-9.2.0 if that makes a difference.
