[Bug 1266348] [NEW] imacros command line breaks debugging information

[pixel]

Public bug reported:

Hello,

  Currently, the gcc ubuntu package has a bug that comes from upstream:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57653


  The effect of the bug is if one compiles a file with the option -imacros,
the filename and all useful debugging information disappears. Here is a
simple example of that:

imacros-test$ cat somefile.c
#warning some warning
imacros-test$ cat macros.h
#define SOME_MACRO
imacros-test$ gcc -c somefile.c
somefile.c:1:2: warning: #warning some warning [-Wcpp]
 #warning some warning
  ^
imacros-test$ gcc -c somefile.c -imacros macros.h
<command-line>:1:2: warning: #warning some warning [-Wcpp]


  This also affects the debugging information embedded within the files,
rendering debugging pretty useless.

  While I am aware this is a bug from upstream, it's been sitting there
for a while with a simple patch. It'd be nice to apply that patch on the
ubuntu package in the meantime.


  Thanks!
