Paolo Carlini:
I was unable to attach the reproducer, as the bugzilla would not accept it due
to it's size. In the meantime, I have uploading it to
http://macdonellba.googlepages.com/_io.i .

Please reduce it to a manageable size. For example, try 'delta', if you don't
have other ways.

------- Comment #4 from macdonellba+gcc at gmail dot com  2009-02-09 22:54 -------
I'm not really sure that this is worth pursuing for me, since I'm a touch
uncertain whether I should expect to have problems with OOM (using over 800MB
of RAM once buffers are cleared) on an macro-laden 79KLOC generated C file,
albeit with most of the preprocessor directives expanding fairly flatly. If
not, I can find another machine to attack the problem of shrinking it with
delta, because it's not exactly a task that will be completed within a day.

Take your time. Please, understand that if a PR is not filed in the proper
form, the chances that a knowledgeable person seriously look into it, sharply
decreases. You can probably find this also useful:

[Bug middle-end/39142] Compilation fails with specialised optimisations.

[rguenth at gcc dot gnu dot org]

------- Comment #6 from rguenth at gcc dot gnu dot org  2009-02-10 10:12 -------
gcc: Internal error: Killed (program cc1)
Please submit a full bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.

Which means that your kernel killed the compiler, likely due to memory
usage issues.  On x86_64 the testcase uses 1.4GB.

Note that the issue is likely the large static initializer of ___lbl_tbl.
See PRs 14179 and 12245.  Removing that initializer the file needs 67MB to
build.

*** This bug has been marked as a duplicate of 12245 ***

Thanks Richard, noticed the Killed too late...
