Package: xgraph
Version: 12.1-12
Severity: important
Tags: patch
User: [email protected]
Usertags: origin-ubuntu maverick ubuntu-patch
The segfault occurs on 64 bit systems; it does not occur on 32 bit systems.
The reason for the segfault is that with the old definition of NE an unadorned
0 is passed as a variadic parameter to variadic functions expecting pointers
(xtb_hort() and xtb_vert() declared in xtb.h)
The compiler has no way to know that is has to convert the 0 constant
to a NULL pointer (and cannot warn as the function is not printf() like).
*** /tmp/tmp_OaVWf
In Ubuntu, we've applied the attached patch to achieve the following:
* change the #define of NE (xtb.h) from 0 to ((xtb_fmt*)0) (LP: #1175701)
We thought you might be interested in doing the same.
