Try changing it to

	volatile guint try_offset;

and rebuilding.

It may be that compilers determine whether something "might be clobbered by 'longjmp' or 'vfork'" based on whether it happens to be in a register or in memory, rather than on what the C specification says about longjmp(), so some compilers, for some target instruction sets, complain, and others don't.
