#9: sizeof computation fails for nested derived types (pointer to array or array of pointers) --------------------+------------------------------------------------------- Reporter: guest | Type: defect Status: new | Priority: normal Milestone: | Component: general Version: 0.15.1 | Keywords: --------------------+------------------------------------------------------- Comment(by guest): I think this may be related: bug.h {{{ typedef char inner_t[32]; typedef struct { inner_t first; inner_t second; } outer_t; }}} bug.chs {{{ module Bug where #include "bug.h" main :: IO () main = print ({# sizeof inner_t #}, {# sizeof outer_t #}) }}} Running c2hs bug.chs (on a 64-bit machine) gives me… {{{ module Bug where main :: IO () main = print (32, 16) }}} Shurely schome mischtake? On the other hand, okay.h {{{ typedef struct { char first[32]; char second[32]; } outer_t; }}} okay.chs {{{ module Okay where #include "okay.h" main :: IO () main = print {# sizeof outer_t #} }}} gives… {{{ module Okay where main :: IO () main = print 64 }}} -- Ticket URL: http://hackage.haskell.org/trac/c2hs/ticket/9#comment:1 c2hs http://www.cse.unsw.edu.au/~chak/haskell/c2hs/ C->Haskell, An Interface Generator for Haskell
