New issue 178 by emil.len...@gmail.com: Constants of type "Single" does not work in some cases. Segmentation fault. http://code.google.com/p/gambas/issues/detail?id=178 1) Describe the problem. Constants of type "Single" does not work in some cases. 2) GIVE THE FOLLOWING INFORMATIONS (if they are appropriate): Version: TRUNK Revision: r4368 3) Provide a little project that reproduces the bug or the crash. MMain: Public Const a As Single = 123.45 Public Sub Main Print MMain.a End 4) If your project needs a database, try to provide it, or part of it. 5) Explain clearly how to reproduce the bug or the crash. Create the Module MMain with the contents above. The interpreter crashes with a segmentation fault. One part of why it is going wrong is the code in gbx_class_load.c: if (TYPE_is_integer(desc->constant.type)) desc->constant.value._integer = cc->_integer.value; else if (desc->constant.type == T_FLOAT) desc->constant.value._float = cc->_float.value; else if (desc->constant.type == T_LONG) desc->constant.value._long = cc->_long.value; else { desc->constant.type = T_CSTRING; desc->constant.value._string = cc->_string.addr; desc->constant.translate = (cc->type == T_CSTRING); } The desc->constant.type is T_SINGLE, so the else part runs.. The actual crash is at VALUE_read(&SP[-1], (void *)&desc->constant.value, desc->constant.type); in gbx_exec_push.c, as it tries to read a string at a bad address instead... ------------------------------------------------------------------------------ Ridiculously easy VDI.
