Unless Emacs has corrupted the memory earlier. Unfortunately,
one cannot use valgrind on Emacs.

I've rebuilt Emacs with -ggdb -O0. I now need to wait for another
crash, hoping that the -O0 won't make the bug disappear.

It was meaningless: I got nothing until __libc_start_main.
With the rebuild (I also installed the -dbg versions of the
libraries, when available in Debian), I should have more
information for the next crash...
