Bug ID: 18132
   Summary: compile/compile-loc2c.c:729: += on uninit data ?
   Product: binutils
   Version: 2.26 (HEAD)
Status: NEW
  Severity: normal
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: dcb314 at hotmail dot com

I just tried to compile trunk binutils with clang. It said

../../src/gdb/compile/compile-loc2c.c:729:6: warning: variable 'uoffset' is
uninitialized when used here [-Wuninitialized]

Source code is

uoffset += dwarf2_per_cu_text_offset (per_cu);

[Bug binutils/18133] New: Infinite recursion while demangling (makes debugging with GDB impossible)

Bug ID: 18133
   Summary: Infinite recursion while demangling (makes debugging
with GDB impossible)
   Product: binutils
   Version: 2.25
Status: NEW
  Severity: critical
  Priority: P2
 Component: binutils

I tried to debug my application that uses Cap'nProto (https://capnproto.org/)
for RPC. I cannot debug my application with GDB since it appears to be crashing
while demangling the symbol
_ZN2kjmlIllNS_1_15NanosecondLabelEEENS_8QuantityIDTmlcvT_Li1EcvT0_Li1EET1_EES4_NS3_IS5_S7_EE:
The Mac OS c++filt binary returns the following:
kj::Quantity
kj::operator*(long, kj::Quantity)



This is the output from GDB:

Reading symbols from ./tests/capnprotorenderer/client...done.
(gdb) break main
Breakpoint 1 at 0x41e7db
(gdb) start
Temporary breakpoint 2 at 0x41e7db

(demangler failed with signal 11)
Unable to dump core, use `ulimit -c unlimited' before executing GDB next time.

(demangler failed with signal 11)
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) 


When I run c++filt I get the following backtrace:
