Comment # 2 on bug 11268 from Peter Wu

Confirmed with the latest code, v1.99.8rc0-214-g59d56bf and GCC 5.1.0.

For some reason size = 0x7fffffffffffffff while I would expect
0xffffffffffffffff for (signed long)-1.

    long size;
    /* ... */
    if ((size = ftell(fp)) < 0) {
        ssl_debug_printf("ssl_load_key: can't ftell file\n");
        g_free(private_key);
        return NULL;
    }
    if (fseek(fp, 0, SEEK_SET) < 0) {
        ssl_debug_printf("ssl_load_key: can't re-fseek file\n");
        g_free(private_key);
        return NULL;
    }
    key.data = "" char *)g_malloc(size);

Minimal reproducer below, strange enough it also shows the 0x7fffffffffffffff
behavior with /usr, but not with /tmp/. Perhaps filesystems can somehow be
opened on Linux as well? (On BSD you can just read directory contents iirc.)

#include <stdio.h>

#define P(r, expr) do { r = (expr); printf("%s = %ld\n", #expr, r); \
    if (r < 0) { puts("FAIL"); return 1; } } while (0)

int main(int argc, char **argv) {
    long r, size;
    if (argc < 2) return 1;
    FILE *fp = fopen(argv[1], "r");
    P(r,    fseek(fp, 0, SEEK_END));
    P(size, ftell(fp));
    P(r,    fseek(fp, 0, SEEK_SET));
    printf("size = %#lx\n", size);
    fclose(fp);
}
