bug#29446: GNU grep 3.1 fails test suite when PCRE lacks JIT

[Thomas Deutschmann]

Hi,

OK, I managed to reproduce the error using pure Debian:

$ mkdir /tmp/pcre-test
$ cd /tmp/pcre-test

$ wget https://ftp.pcre.org/pub/pcre/pcre-8.43.tar.gz
$ tar -xaf pcre-8.43.tar.gz

$ cd pcre-8.43/
$ ./configure --prefix=/tmp/pcre-test/build \
--with-match-limit-recursion=8192 \
--enable-pcregrep-libbz2 \
--enable-cpp \
--disable-jit \
--disable-pcregrep-jit \
--disable-pcre16 \
--disable-pcre32 \
--disable-pcretest-libedit \
--enable-pcretest-libreadline \
--disable-static \
--enable-utf \
--enable-unicode-properties \
--enable-pcregrep-libz \
--enable-pcre8 \
--enable-shared

$ make
$ make install

$ cd ..
$ wget https://ftp.gnu.org/gnu/grep/grep-3.3.tar.xz
$ tar -xaf grep-3.3.tar.xz
$ cd grep-3.3/
$ PKG_CONFIG_PATH=/tmp/pcre-test/build/lib/pkgconfig ./configure
$ make

# Now check src/grep
$ lddtree src/grep
grep => src/grep (interpreter => /lib64/ld-linux-x86-64.so.2)
    libpcre.so.1 => not found
[...]

$ export LD_LIBRARY_PATH=/tmp/pcre-test/build/lib

# Check with lddtree again to be sure our local pcre build is being used
$ lddtree src/grep
grep => src/grep (interpreter => /lib64/ld-linux-x86-64.so.2)
    libpcre.so.1 => /tmp/pcre-test/build/lib/libpcre.so.1
[...]

# Test that src/grep works:
$ echo . | src/grep -P .

# Now run test which will fail:
$ make check TESTS=pcre-jitstack
