Well, then, I don't know. Putting libflashplayer.so back in, I don't have to work very hard to make flash bomb out. Even after letting abrt download about a hundred debuginfos and install them, it does not produce a very useful backtrace:

The only clue is that Firefox here dies with SIGILL:

As I understand it, flash gets compiled to native code. This is a relatively
old Opteron:
processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 5 model name : AMD Opteron(tm) Processor 240 stepping : 1I suspect that some bits of flash code get compiled into x86_64 instructions that are not implemented on my older CPU. So, although I can watch video on youboob, apparently most other flash sites get compiled into x86_64 code that won't work on my older CPU.
Oh well.
