gcc-3.1 ICE on ppc-linux, regression wrt 2.95

[Michal Moskal <malekith at pld-linux dot org>]

Following code, compiled with 'gcc -O2 -c' :

#define NULL 0
#define PATH_MAX 1024
extern int verbose;

int pkgdir_update(int *npatches) 
{
    char            foo[PATH_MAX], tmpath[PATH_MAX], path[PATH_MAX];
    char            *linebuf = NULL;
    int             line_size = 0, nread, nerr = 0;

    
    while ((nread = getline(&linebuf, &line_size, NULL)) > 0) {
        char *p;

        if ((p = strchr(p, ' ')) == NULL) {
            nerr++;
            break;
        }
        (*npatches)++;
    }
    

    if (*npatches == 0)         /* outdated and no patches */
       nerr++;

    if (nerr == 0) {
        if (vf_localdirpath(tmpath, sizeof(tmpath), path) < (int)sizeof(tmpath)) {
            verbose--; /* verbosity need to be reorganized... */
            rm_dir_files(tmpath);
           verbose++;
        }
        
        
    }
    
    return nerr == 0;
}

causes gcc 3.1 20020415 to ICE.

Reading specs from /usr/lib/gcc-lib/ppc-pld-linux/3.1/specs
Configured with: ../configure --prefix=/usr --infodir=/usr/share/info

Thread model: posix
gcc version 3.1 20020415 (prerelease)

Example was destiled from bigger source (poldek pkg managment tool by
Pawel Gajda), I'm unable to cut it down.

It compiles fine with gcc 2.95.
