Source: dnprogs Version: 2.50.1 Hi Christine,
As you probably know, GCC 4.4 is more aggressive by default than previous versions about taking advantage of C99 aliasing rules to speed up code [1]. Building dnprogs produces warnings related to this regarding dnet_pton1 (dnet_pton.c line 60) and dnet_ntop1 (dnet_ntop.c line 49). Problems from unexpected optimization can be hard to debug, so I thought I should check in with you about these. A quick fix is to disable the optimization with -fno-strict-aliasing. Of course, it is much better to fix the strict aliasing violation itself, by copying char by char (e.g., with memcpy), using a union to make the aliasing explicit, or paraphrasing the code to avoid type-punning altogether. I noticed this while trying to build your package under hercules (s390 emulator). It’s still chugging away. Please let me know if there is any more information I can provide to help track this down.
