Hi,
While porting and using swftools to OpenBSD we've run into a few bugs
with the swftools binaries.
The developer reporting this first issue mentioned crashes with pretty
much anything used with swfstrings.
Program received signal SIGBUS, Bus error.
swf_SetTagPos (t=0xd0d0d0d0d0d0d0d0, pos=0) at rfxswf.c:68

) at swfstrings.c:230
and a proposed patch by the developer.

And a crash with swfc found while running the Gnash testsuite.
