[Gnash-dev] --enable-jemalloc Problem

[Udo Giacomozzi]

Rob, this is for you:   ;-)

I compiled Gnash on Debian 4 standard with these options:

./configure --with-extensions=fileio --disable-debugger
--enable-renderer=agg --enable-gui=fb --disable-cygnal
--with-pixelformat=BGRA32,BGR24 --enable-fps-debug --disable-klash
--enable-media=GST --disable-static --with-gcc-arch=i486
--enable-jemalloc CXX=ccache g++

fb-gnash aborts right at the start:

- doesn't happen with GTK Gnash
- fileio doesn't matter
- same effect on three different machines and with different movies
- using current HEAD, of course


I modified the code print the value in setReachable() (that's where
it aborts) and after that it just aborts with:

lt-fb-gnash: character.cpp:912: virtual void gnash::character::destroy(): 
Assertion `!_destroyed' failed.

...while which() always returned 1. So very likely there is memory
corruption...
