[x264-devel] [Bug Report] Segmentation Fault in 2nd Pass

[Rodolfo J. Quesada Zumbado]

Hi again,

I have never tried to debug a shared library from within the loader 
program, besides, I haven't used gdb for a while, and I only know the 
basics... But I compiled x264 with --enable-debug and invoked "gdb 
--args mencoder -ovc x264 ...." and this is what I got:

...
Lots of MEncoder output...
...

Program received signal SIGSEGV, Segmentation fault.

This is a second pass run (pass=2).
