Still fails but now generated code is invalid: {{{ /tmp/ghc31859_0/ghc_4.hc:352:5: error: error: 'c2l_entry' used but never defined [-Werror] IF_(c2l_entry); ^ | }}} Generated code: {{{ FN_(stg_catch_entry) { W_ _c2g; _c2h: _c2g = R1.w; R1.w = *((P_)(_c2g+8)); Sp[-1] = *((P_)(_c2g+16)); Sp=Sp-1; JMP_((W_)&stg_catchzh); } const StgWord stg_catch_info[]__attribute__((aligned(8)))= { (W_)&stg_catch_entry, 0x2UL, 0x8UL }; IF_(c2l_entry); FN_(stg_catchzh) { _c2p: Sp[-1] = R1.w; Sp=Sp-2; JMP_((W_)&c2l_entry); } }}} It should have been '''stg_catch_entry''' instead of '''c2l_entry'''. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14264#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
