Description David Binderman 2005-01-12 15:26:23 UTC
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 11:02:44 UTC
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 12:43:30 UTC
Yes, I did :) the surrounding source code you pointed out looks like modified.
that's why I asked you now.

Comment 4 Akira TAGOH 2005-12-27 03:46:51 UTC
Fixed in 1.8.4-1.
