 Posted: Sun Mar 26, 2017 9:43 am Post subject: Seamonkey-2.46-r1/Firefox-52 crash with Segmentation fault |
 |
|
Good morning,
after my 2nd frustrating attempt to give Pulseaudio a chance, I removed that piece of crap from my machine again. Pulseaudio simply doesn't seem to be able to handle the mixer controls of the Asus Xonar soundcards. No chance to get the Headphone volume control. And yeah, be happy, this problem exists already for ages. After altering the mixer number from 2 to 8 nothing changed in alsamixer or KMix, but my favourite game in Wine (Spider Solitaire) didn't work anymore. Wine simply hangs.
After removing Pulseaudio (incl. Use-flag) and recompiling the concerned packages (inc. Seamonkey and Firefox) both programs refuse to run.
The short version:
| firefox: | | Segmentation fault (core dumped) |
The long version:
| strace -f firefox: | …

I didn't try to reinstall Pulseaudio. I don't want to pollute my system again. Not sure if this problem is related to this thread.

Oh yeah ! |
They're all flags that -march=native would enable, and all the -mno-* options suggest that's exactly where he got them from, all perfectly "safe", so what's your point?

So why not just use -march=native ?
Package maintainers intentionally disable one or several implied GCC flags on some packages, often because of stability or compilation problems. Forcing them is at best useless, at worst a source of such headaches. I wouldn't be surprised if firefox/seamonkey run well without all that stuff.
That said, this is an unstable Gentoo system. Perhaps GCC 5.4 is a problem by itself, for example. |

Two reasons come immediately to mind. First, using -march=native means the compiler works it out every single time. In theory, this ought to be a few quick table lookups and not be particularly expensive. Second, distcc does not distribute commands built with -march=native. For users who get most of their compilation power from the distributed hosts, distcc can be a massive win, so forfeiting it is extremely undesirable. |

Hu and Sadako are completely right. It's just an expaned march=native. One reason ist distcc. A second reason is cross-compiling in a chroot, where march=native is even more complicated.
You can get the flags by:
| Code: | | gcc -### -march=native -E /usr/include/stdlib.h 2>&1 | grep "/usr/libexec/gcc/.*cc1" |

Firefox and Seamonkey installed in the version before without any problems.

Of course, it's an unstable system. There have to be people to test unstable software and file bug reports. Software isn't becoming stable by itself. |

how about using firefox-bin?
afaik -mno- means disable of ... check gcc manual when you want to know more.
-mno-xop => xop is bulldozer amd cpu only feature, not ryzen ! not intel! => so its disabled for example |

Ok, my bad.

I know.
I reacted too fast, sorry for the noise. |
