Bug#445336: [hppa] ICE when building asterisk

[Faidon Liambotis]

Package: gcc-4.2
Version: 4.2.1-5
Severity: grave

As can be witnessed from the build logs on buildd.d.o[1], gcc-4.2
produces an ICE when trying to build pbx_dundi.c on hppa.

The log doesn't show the gcc arguments (upstream Makefiles have the "pretty"
build feature, disabled in our trunk). These are:

> gcc -o pbx_dundi.o -c pbx/pbx_dundi.c \
>     -pthread -Iinclude  -pipe -Wall \
>     -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations \
>     -g3 -include include/asterisk/autoconfig.h -O2 -fPIC \
>     -DAST_MODULE=\"pbx_dundi\"
> pbx/pbx_dundi.c: In function 'handle_command_response':
> pbx/pbx_dundi.c:1885: internal compiler error: in delete_output_reload,
> at reload1.c:7958

The build is a bit tricky because of autoconf magic etc.
There is an extracted source that will build the file using the above
arguments on paer.debian.org:~paravoid/asterisk-1.4.11~dfsg

Unfortunately, line 1885 is a closing brace for a *HUGE* function, so it
really hard to pinpoint this further.

However, I've tried with gcc-4.1 and gcc-snapshot and they both manage to
compile without problems; may be the bug is found and fixed upstream
already.

Thanks,
Faidon
