After two months, it's coming back.
Regarding: https://roundup.ffmpeg.org/issue803

How to work around it??

I've compiled old 3.97 lame using gcc 4.3.2.
Compiled FFmpeg version SVN-r22626 against it using gcc 4.3.2

Tried disabling all optimizations (directly in ./configure of lame, setting
-O0 CFLAGS everywhere).
Scanned all dirs for all lame installation and removed old files.
Recompiled and installed lame 3.97 in proper libdirs


Every time I try to encode with mp3 ffmpeg segfaults:
---------
