[Bug debug/65549] [4.9/5/6 Regression] crash in htab_hash_string with -flto -g
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65549 Ferdinand changed: What|Removed |Added CC||ferdinandw+gcc at gmail dot com --- Comment #21 from Ferdinand --- I'm running into this when building firefox beta tree with lto. The release tree is working alright, but on beta it crashes with this bug's stacktrace. Is it only with -g? I'm using -g0 for the most part.
[Bug debug/65549] [4.9/5/6 Regression] crash in htab_hash_string with -flto -g
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65549 --- Comment #22 from Ferdinand --- Now that I understand the bug, of course I notice (too late) that my way of setting -g0 wasn't taking effect in the beta tree, the way it was before. So that explains that, but still this crash is happening with just -flto=4 (and default -flto-partition=balanced) for me. That means, at the moment, it's not latent for building firefox.

Here's a reduced version that gives me an ICE on FC5's gcc 4.1.0 with:
g++ -O -c 3ddeskd.cpp
=
class Config {
public:
int texture_size;
int bg_size;
int autoacquire;
};
class Face {
public:
void load_texture_data (int texture_size) {
extern Config *cfg;
cfg->bg_size++;
}
};
class FaceSet {
private:
Face faces;
public:
void load_texture_data (int size) {
faces.load_texture_data(size);
};
};
Config *cfg;
FaceSet *face_set;
void load_background_image(void)
{
cfg->bg_size++;
extern Config *cfg;
cfg->autoacquire++;
}
void
humbug ()
{
if (cfg->autoacquire)
face_set->load_texture_data(cfg->texture_size);
}

Sorry for the bugspam, but I noticed it could be reduced a bit more.
=
struct Config {
int bg_size;
int autoacquire;
