...592 that was referred by another DIE 0x00000883 but somehow DIE 0x00000592 was not emitted. This could be a bug in DwarfDebug.cpp or how debug info is generated by FE. In DwarfDebug.cpp, you'll see code like addDIEEntry(VariableSpecDIE, dwarf::DW_AT_specification, dwarf::DW_FORM_ref4, VariableDIE); Here VariableSpecDIE is referring VariableDIE, but VariableDIE is missing from the output. There are other uses of DW_FORM_ref4 also. So check in our dwarfdump output what is 0x00000883 and set appropriate breakpoint in debugger and see why it is not reaching to DwarfDebug::emitDIE(). - Deva...

I've been trying to track down the problem with the DWARF info that is being emitted by my front end, which has been broken for about a month now. Here's what happens when I attempt to use gdb to debug one of my programs on OS X: gdb stack crawl at point of internal error: [ 0 ] /usr/libexec/gdb/gdb-i386-apple-darwin (align_down+0x0) [0x122300] [ 1 ] /usr/libexec/gdb/gdb-i386-apple-darwin
