Bug description

Here is the command line of ocamlopt.opt

ocamlopt.opt -inline 10 -verbose -linkall -o mlnet \ bigarray.cmxa unix.cmxa str.cmxa -ccopt " " -cclib "-lz " -cclib -lbz2 -ccopt "-pthread" \ \ -cclib "-lgd -ljpeg -lfreetype -lpng12 -lz -lm" -ccopt "-L/usr/lib" \ -cc 'g++' -ccopt '-g -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer' \ -cclib -lmagic \ -I build build/cdk.cmxa build/magic.cmxa build/common.cmxa build/client.cmxa build/core.cmxa build/driver.cmxa src/daemon/common/commonMain.cmx

which results into these calls:

• as -o '/tmp/camlstartup71aed3.o' '/tmp/camlstartup2827b1.s'
• gcc -o 'mlnet' -I'/usr/local/lib/ocaml' '-Lbuild' '-L/usr/local/lib/ocaml' '/tmp/camlstartup71aed3.o' '/usr/local/lib/ocaml/std_exit.o' 'src/daemon/common/commonMain.o' 'build/driver.a' 'build/core.a' 'build/client.a' 'build/common.a' 'build/magic.a' 'build/cdk.a' '/usr/local/lib/ocaml/str.a' '/usr/local/lib/ocaml/unix.a' '/usr/local/lib/ocaml/bigarray.a' '/usr/local/lib/ocaml/stdlib.a' 'src/utils/cdk/gdstubs.o' '-lz' '-lbz2' 'src/networks/direct_connect/che3_c.o' 'src/networks/fasttrack/enc_type_1.o' 'src/networks/fasttrack/enc_type_2.o' 'src/networks/fasttrack/enc_type_20.o' 'src/networks/fasttrack/enc_type_80.o' 'src/networks/fasttrack/fst_crypt.o' 'src/networks/fasttrack/fst_crypt_ml.o' 'src/utils/lib/CryptoPP.o' 'src/utils/lib/CryptoPP_stubs.o' '-lz' '-lbz2' '-lz' '-lbz2' 'src/daemon/common/commonHasher_c.o' '-lz' '-lbz2' 'src/utils/lib/magiclib_stub.o' '-lz' '-lbz2' 'src/utils/cdk/zlibstubs.o' 'src/utils/cdk/heap_c.o' 'src/config/unix/os_stubs_c.o' 'src/utils/lib/fst_hash.o' 'src/utils/lib/md4_comp.o' 'src/utils/lib/md4_c.o' 'src/utils/lib/charsetstubs.o' 'src/utils/lib/md5_c.o' 'src/utils/lib/sha1_c.o' 'src/utils/lib/tiger.o' 'src/utils/lib/stubs_c.o' '-lz' '-lbz2' '-lstr' '-lunix' '-lbigarray' '-lz' '-lbz2' '-lgd' '-ljpeg' '-lfreetype' '-lpng12' '-lz' '-lm' '-lmagic' '/usr/local/lib/ocaml/libasmrun.a' -lm -ldl -pthread -L/usr/lib -g -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -pthread -pthread -pthread -pthread -pthread -pthread

It leads to linking problems with C++ code. Using the same command with Ocaml 3.10.2 works.
