Comment (by MichaelCrawford):
There was just one warning, line 766 of JPEGTranslator.cpp, outType might
be clobbered by 'longjmp' or 'vfork'.
outType is a uint32, and so is likely stored in a register. The setjmp
stores the registeres in the jmp_buf. The solution appears to be to
declare outType volatile, so it is stored on the stack. In this
particular routine doing so will have a negligible effect on performance
