Top Forums Programming Why does this example C code run and yet SHOULD either not compile or give a segmentation fault? Post 303033014 by Corona688 on Thursday 28th of March 2019 11:28:12 AM

Further, doing things you didn't ask the compiler to do is begging for trouble. The compiler loves to remove things you "don't use", to the point that if you never touch a variable in your program, it might optimize it away completely and use hardcoded values instead. You have to make these variables 'volatile' to force the compiler to not do anything smart and helpful for you.

NAME
g-ir-compiler - typelib compiler. SYNOPSIS
g-ir-compiler [OPTION...] GIRFILE DESCRIPTION
g-ir-compiler converts one or more GIR files into one or more typelib. It can either emit the raw typelib blob (default behavior) or C code (--code). The output will be written to standard output unless the --output is specified. OPTIONS
---help Show help options ---code Emit C code which is suitable for including in a shared library instead of a raw typelib. ---output=FILENAME Save the resulting output in FILENAME. ---verbose Show verbose messages ---debug Show debug messages ---no-init Do not include an initialization snippet to register the typelib in the respository. This can only be used if --code is also speci- fied. ---includedir=DIRECTORY Adds a directory which will be used to find includes inside the GIR format. ---module=MODULE FIXME ---shared-library=FILENAME Specifies the shared library where the symbols in the typelib can be found. The name of the library should not contain the leading lib prefix nor the ending shared library suffix. BUGS Report bugs at http://bugzilla.gnome.org/ in the glib product and introspection component.
