This version of gcc is known to generate incorrect code for the OCaml runtime system on some Intel x86 machines. (The symptom is a crash of boot/ocamlc when compiling stdlib/pervasives.mli.) In particular, the version of gcc 2.7.2.1 that comes with Linux RedHat 4.x / Intel is affected by this problem. Other Linux distributions might also be affected. If you are using one of these configurations, you are strongly advised to use another version of gcc, such as 2.95, which are known to work well with OCaml. Press to proceed or to stop. EOF read reply;; 2.96*) cat <<'EOF' WARNING: you are using gcc version 2.96 on an Intel x86 processor. Certain patched versions of gcc 2.96 are known to generate incorrect code for the OCaml runtime system. (The symptom is a segmentation violation on boot/ocamlc.) Those incorrectly patched versions can be found in RedHat 7.2 and Mandrake 8.0 and 8.1; other Linux distributions might also be affected. (See bug #57760 on bugzilla.redhat.com) Auto-configuration will now select gcc compiler flags that work around the problem. Still, if you observe segmentation faults while running ocamlc or ocamlopt, you are advised to try another version of gcc, such as 2.95.3 or 3.2.
