This happens to me as well.

Analyzing the problem, I found that the called function "_savegpr_30" has a non-standard calling convention; it takes its input parameter in r11. However, the call to the function goes through the PLT (a dynamic call), which clobbers r11. This looks like a GCC bug.

The following GCC patch might be relevant: http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00264.html

[Marcus Comstedt (marcus-mc)]

As a workaround, changing

  CFLAGS += -Os

to

  CFLAGS += -O

in debian/rules produces a working gnash.

[Marcus Comstedt (marcus-mc)]

-O2 also works fine, it's just -Os that is bugged.

Does this still occur with the version of gcc in lucid?

Can you please test with the latest version of the gnash package in the gnash team PPA (https://edge.launchpad.net/~gnash/+archive/ppa?field.series_filter=)?

[Sindhudweep Sarkar (sindhudweep-sarkar)]

Disregard my brainfart. Obviously the ppa doesn't produce packages for ppc.

[Marcus Comstedt (marcus-mc)]

Well, I tried the 0.8.6-0ubuntu2 package published in Lucid, an that one seems to work at least.

[Marcus Comstedt (marcus-mc)]

Also, the gcc bug has been fixed in karmic-updates (by gcc-4.4 version 4.4.1-4ubuntu9),
so building the karmic package from source on an up-to-date karmic system also produces
a working binary.
