However, there are probably still a lot of broken compilers installed, so maybe it would be a good idea to put a workaround in gflags. The for_eh_or_skip parameter controls whether register numbers are converted using DWARF2_FRAME_REG_OUT, which is needed in the case that hard reg numbers have been processed via DWARF_FRAME_REGNUM (i.e. I realize this has more questions than answers ... :/ Comment 8 Jason Merrill 2011-12-09 18:22:38 UTC We shouldn't be emitting anything for that nested function declaration in the concrete instance Agreed.

As far as I understood imposing constraints like this to the partitioner is hard because either you implement the same constraints into the inliner as well or you eventually blow up https://bugzilla.redhat.com/show_bug.cgi?id=746405 Adding these 2 lines always fixes the test case provided by mthuurne (for me). add_AT_flag (tdie, DW_AT_external, 1); ! gflags member schuhschuh commented Mar 24, 2015 Comment #2 originally posted by schuhschuh on 2008-08-30T09:07:00.000Z: I use this as the source file (define.cpp): #include DEFINE_string(name, "default", "help"); And the following command

All supported gcc versions are affected. useful reference That RECORD_TYPE has TYPE_CONTEXT the main FUNCTION_DECL, which is apparently emitted in partition 1 and so lookup_decl_die for it returns NULL (there is not even a stub DW_TAG_subprogram emitted in the symbolic debug info), by setting the parameter < 0. Please include the complete backtrace with any bug report.

See for instructions. The above patch fixes this bug. This should be suppressed for the cases that have not been converted (i.e. http://renderq.net/internal-compiler/internal-compiler-error-in-dwarf2out-finish-at-dwarf2out-c.php It happens only when "-g" is passed to GCC, so the problem is most likely in the generation of the debug symbols ("dwarf2out.c" also suggests this).

gen_type_die_with_usage gets a TEMPLATE_TYPE_PARM which doesn't know how to handle. Comment 3 Jakub Jelinek 2015-03-30 11:17:15 UTC From quick look, the problem is that we attempt to generate DIE for a RECORD_TYPE __lambda5 in partition 2. for unwind info).
