Hi! I think I found bug in gcc 2.95.2 code generation. look at flex generated code( flex -oyylex2.cc yylex2.y ): ---------------------------- . . . static void *yy_flex_alloc YY_PROTO(( yy_size_t )); static void *yy_flex_realloc YY_PROTO(( void *, yy_size_t )); . . . #ifdef YY_USE_PROTOS static void *yy_flex_alloc( yy_size_t size ) #else static void *yy_flex_alloc( size ) yy_size_t size; #endif { . . . #ifdef YY_USE_PROTOS static void *yy_flex_realloc( void *ptr, yy_size_t size ) #else static void *yy_flex_realloc( ptr, size ) void *ptr; yy_size_t size; #endif { . . . ---------------------------- and now assembler code generated by( g++ -S yylex2.cc ) . . . .def _yy_flex_alloc__FUi AT 4; .scl 2; .type 32; .endef _yy_flex_alloc__FUi AT 4: ^^^ why??? . . . .def _yy_flex_realloc__FPvUi; .scl 3; .type 32; .endef _yy_flex_realloc__FPvUi: . . . ---------------------------- I cannot understand why @4 appended to yy_flex_alloc and not appended to yy_flex_realloc. Functions definitions look same to me. All calls to yy_flex_alloc are right ( call _yy_flex_alloc__FUi ) Thank you. Alexey Voinov -- Want to unsubscribe from this list?
