Description David Binderman 2005-01-12 10:26:23 EST
Description of problem:

I just tried to compile package ruby-1.8.2-1 from 
Redhat Fedora development tree.

The compiler said

ossl_ocsp.c(264): remark #592: variable "req" is used before its value
is set

The source code is

    OCSP_REQUEST *req;
    VALUE str;
    unsigned char *p;
    long len;

    if((len = i2d_OCSP_REQUEST(req, NULL)) <= 0)

Suggest init local variable "req" before first use.


rubyext.c(831): remark #592: variable "size" is used before its value
is set

The source code is

        int size = NUM2INT(rb_funcall(size, s_to_i, 0));

The trouble with this code is that there is a parameter called size,
and a local variable also called size. Suggest code re-work.

Please test the latest version of ruby, 1.8.3-2.
Comment 2 David Binderman 2005-09-26 07:02:44 EDT
The machine with the Intel C compiler on it died.

I think if you want to verify that this bug is fixed in the latest 
release, I can recommend a quick visual inspection of the source code.
Comment 3 Akira TAGOH 2005-09-26 08:43:30 EDT
Yes, I did :) the surrounding source code you pointed out looks like modified.
that's why I asked you now.
Comment 4 Akira TAGOH 2005-12-26 22:46:51 EST
Fixed in 1.8.4-1.
