#10885: Crashes on FFI calls to Visual Studio-built C library -------------------------------------+------------------------------------- Reporter: mwu | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.1 Resolution: | Keywords: Operating System: Windows | Architecture: x86_64 | (amd64) Type of failure: Runtime crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): I hardly know anything about Windows and its calling conventions (for example I have no idea how `OSMinGW32` is a possible platform when compiling 64-bit code) but a while ago I noticed at https://en.wikipedia.org/wiki/X86_calling_conventions#Microsoft_x64_calling_... something about a shadow space which as far as I can see we don't take into account in `genCCall64'`. Could this be the cause? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10885#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
