Summary: Another DWARF line number fix
Product: D
Version: 1.051
Platform: Other
OS/Version: Linux
Status: NEW
Keywords: patch, wrong-code
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: nfxjfg gmail.com
There's a small detail wrong with the DWARF line number information: your code
makes wrong assumptions when the line number state machine register state is
reset. The DWARF specification says it's reset after DW_LNE_end_sequence, but
as your code resets the register state, it doesn't emit a DW_LNE_end_sequence.
The result is that some address/line number ranges in .debug_line are
completely bogus.
This patch provides a simple fix by moving DW_LNE_end_sequence to where it is
appropriate.
(Note that some DWARF consumers, such as GNU BFD, are able to deal with the
buggy line number information.)
(I hope the wrong-code keyword isn't inappropriate here.)
Note that this bug is unrelated to bug 3214, which has yet to be fixed.

Please, don't close bugs until a fix is proven to work. There is no DMD release
that has this bug fixed yet.
