Red Hat Bugzilla – Bug 149463
local variable used before set
Last modified: 2007-11-30 17:11:00 EST
Description of problem: I just tried to compile package conglomerate-0.9.0-1 from Redhat Fedora Extras development tree. The compiler said cong-error-file-save.c(162): remark #592: variable "volume_capacity" is used before its value is set The source code is char* volume_capacity_string = gnome_vfs_format_file_size_for_display(volume_capacity); Suggest initialise volume_capacity before first use. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
WFM, no error on FC3. Can you provide some additional information: which release of Fedora are you using? are you using any kind of build system? is there anything custom about your system (not core + extras)?
He's looking for compiler warnings, probably adding -Wall to rpm optflags and rebuilding all of Extras. This one is not a bug. Rationale given in lines 152-159.
>are you using any kind of build system? The clue is in the remark message - I hope you can recognise that it isn't a message produced by the GNU C compiler. In fact, I am using the most excellent Intel C compiler - better messages (see above) and better code generation. For conglomerate, this does appear to be code that is "work in progress" - plenty of commented out bits.
