I will attach a gdb output as well as a patch that seems to fix this. This patch is the alignment fix merged with the pre-existing NetBSD patch. Using this patch - I was able to build and also run a few small command line tests.

Why is the change to the cpool size necessary?

[vom513]

JSValue can hold a double/int64, needs 8-byte alignment. cpool_offset was computed with no rounding, so on SPARC the array lands on a 4-but-not-8 boundary and any load traps SIGBUS. Just round it up to 8 before placing the array.

Having said that - I'm happy to try a patch from one of you maintainers. This just happened to work for me to get this to build and working. Happy to test on NetBSD/sparc. Thanks.
