[Bug c/19077] New: Internal compiler error compiling MPlayer

[M dot Kosmulski at elka dot pw dot edu dot pl]

When compiling MPlayer 1.0pre5, an internal compiler error is generated.
Normally the program is compiled using make, so below is just the single file
that causes that error:

 Neither of the reduced test cases causes any segfault on powerpc-linux for me
with gcc 4.0.

I can reproduce this with 3.4.0 and I get the following backtrace:
#0  0x0083b41e in _int_free () from /lib/tls/libc.so.6

But with an slightly old 4.0.0 (two months old, 20041124), I cannot reproduce this with either of the 
reduced testcases.

Ran it through valgrind to track down the memory errors and then started
hunting. Testing a patch currently. valgrind returns no errors after patch.
