Only you can answer if 3c5fe5b works ok, if it does, 
please test a1bcc76.
(In case this is not obvious: Because of the 
peculiarities of the FFmpeg project, your 
script may save you some time but will not 
work the way you are used to from other git 
repositories, I therefore suggest manual 

If compilation really takes >10minutes, you can 
try the following configure line with current 
git head:
$ ./configure --disable-everything --enable-protocol=file 
--enable-demuxer=mov --enable-parser=h264 --enable-decoder=h264

(You of course have to add the cross-compilation options.)

This assumes your crashing test file is a mov file, 
adapt the --enable-demuxer entry in case it is not.

You can also test --disable-optimizations, this speeds 
compilation up significantly but may hide the bug: It 
is probably ok in your case but who knows.

(This will work even less with a script because some 
revisions will need additional --enable-* options to 
succeed compilation.)
