Bug#342126: gcc-4.0: gcc generates bad assembly code for simple code

[Vagner Pedrotti <vpbra@yahoo.com.br>]

Package: gcc-4.0
Version: 4.0.2-5
Severity: normal

When I compile the following simple code, gcc fails with:
/tmp/ccySlj9q.s: Assembler messages:
/tmp/ccySlj9q.s:56: Error: missing or invalid immediate expression `' 
taken as 0
/tmp/ccySlj9q.s:56: Error: suffix or operands invalid for `call'

I've ran gcc -S in the code and I found a "call $" in the compiled code 
for parse_cmd.

Here is the code:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <string.h>

struct sstate {
 int daemon;
 int run;
 int level;
 struct timespec sleep;
 int sleep_h;
 int max_level;
 int min_level;
 int total_states;
};

typedef struct sstate tstate;
static int parse_cmd(char *argv[], int argc, tstate *state) {
 int i = 1;
 while (i < argc) {
   char *op = argv[i++];
   if (strcmp(op, "-i") == 0) {
     if (i >= argc || sscanf(argv[i++], "%d", $(state->sleep_h)) != 1) {
       return 0;
     }
   } else if (strcmp(op, "-h") == 0) {
     if (i >= argc || sscanf(argv[i++], "%d", &state->max_level) != 1) {
       return 0;
     }
   } else if (strcmp(op, "-l") == 0) {
     if (i >= argc || sscanf(argv[i++], "%d", &state->min_level) != 1) {
       return 0;
     }
   } else if (strcmp(op, "-f") == 0) {
     state->daemon = 0;
   } else {
     return 0;
   }
 }
 return 1;
}

tstate state;

int main(int argc, char *argv[]) {
 if (! parse_cmd(argv, argc, &state)) {
   exit(1);
 }
 return 0;
}
