Looks like another one for Andrew MacLeod.
I'm keeping him busy with these ICEs :-)

Here is a reduced testcase:
int get_chunk(int);
int chunks_number;
void seek_close_chunk(void);
int recover_errors;
#define SKIP_CHUNKS 1
void
get_chunk_name(int chunk_num)
{
int chkid;
int chunks=0;
int last_chunk=0;
try
{
int chunks_left=-1;
int chksize;
for(;(chunks_left--)&&(chksize=get_chunk(chkid));last_chunk=chunks)
{
if (chunks++==chunk_num) { break; }
seek_close_chunk();
}
}
catch(int ex) {
if (chunks_number < 0)
chunks_number=(recover_errors>SKIP_CHUNKS)?chunks:last_chunk;
};
}

This is an old one.

Hmm, this looks like into SSA problem because disabling all tree optimization does nothing to ICE.
