firefox-1.0 crash on 5.3-stable, running flash plugin: possibleproblem in pthreads (Nov 8th)

Thu Nov 18 12:04:45 PST 2004

Hello, I found firefox-1.0 crashes with signal 11, Segmentation fault, 
when using flashplugin.
It happens accessing this site: http://www.globo.com. The plugin seems 
to work well in other sites, but I did not test many.
The same site can be accessed without the plugin (no flash effects, of 
course) and firefox doesn't crash.
GDB backtrace points out libpthread functions before crashing.
The problem is triggered by the flashplugin, but I am not sure whether 
it is a pthread bug or just a misuse of the library routines.
