I am looking for some help with segfault when passing a struct to a C-API via @ccall. I created an immutable struct inside a Ref(), and then call something like @ccall lib.somefunc(myref::Ptr{MyStruct}).... This seems to work, but then when the Julia function returns I get an EXCEPTION_ACCESS_VIOLATION at 0x2a088a9 -- jl_gc_pool_alloc.

The struct I was passing in needed a buffer. I used a Julia array directly as a field in that struct, when in fact I needed to use pointer(array).
Thanks!
