Segmentation fault on firefox and thunderbird[已解决]

shikihyx

不知道什么时候开始的
这两天使用ff 还有thunderbird都会在特定的情况自动退出
浏览网页时如果右键>图片另存为 或者下载东西 点保存
立刻就报Segmentation fault 然后自动关闭
thunderbird也是 没有升级3.0斯可以打开邮件的
升级了3。0以后打开邮件就会报错误
同样退出 ...

想了想 前几天使用 -march=native -O2 -pipe
从新emerge -esystem&& world
难道是或者-fomit-frame-pointer
出问题 ？ 依稀记得一个地方说过-mfpmath=sse其实是多余加上去的
但是还是加了 不知道问题出至于哪里 ...
望各位兄弟指点...

我不確定，可能和新的glibc有關。前一段时间在IRC上有人讨论。你关注一下吧。

不要考虑降级glibc的事，portage不让。

成 。郁闷...

blackwhite

你把firefox再编译一次看看，你说的那几个优化，我在用，没有发现问题。

shikihyx

-march=native -O2 -pipe -fomit-frame-pointer
重新编译了整个world 已经没事了 ...
-mfpmath=sse  难道真的是这个问题哦 ...？

fender010

是优化过度导致某些firefox中的潜在的bug暴露出来了。

cofairy

我前两天做的两次 LFS （jhalfs）也出了同样的问题，找不到原因，没解决。
与 LZ 不同的是 -O3 -pipe
难道要用 -O2？

coderoar

-mfpmath=sse只用了一次就取消了，看看这个[color="Blue"]Safe Cflags吧。

我用的是-O2
出问题的原因是-mfpmath=sse
