Bug ID: 70599
Summary: Crash when adding debug symbols to a program making
heavy use of nested templates.
Product: gcc
Version: 5.3.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: graemehattan7 at hotmail dot com
Target Milestone: ---
This issue was found while trying to compile the source code for the aprinter
3D printer firmware - https://github.com/ambrop72/aprinter
Normal compilation works fine, the issue is when I try to add the -g option for
a debug build. When I do this, the compilation resources increase until 100%
cpu and memory are used. Eventually I get the following message:
arm-none-eabi-gcc: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
The aprinter software makes heavy use of nested templates, I imagine that this
is what trigger the issue. I have attached the pre-processor output from the
file that fails. Unfortunately this is quite large due to the number of headers
defining template classes.
The issue can be reproduced with the following command -
arm-none-eabi-gcc -g -x c++ -c -mcpu=cortex-m3 -mthumb -Wall -Wextra
-Wfatal-errors -Wno-unused -Wno-sign-compare -std=c++11 -fno-access-control
aprinter-nixbuild.ii
Note that there will be a lot of compiler warnings produced (~750 MB!) if the
-Wno-unused flag is removed. This is in part because of the very long type
names produced by template nesting.
Additional info:
arm-none-eabi-gcc -v
Using built-in specs.

The compiler was built via the nix-build derivation included in aprinter -
https://github.com/ambrop72/aprinter/blob/master/nix/gcc-arm-embedded-fromsrc.nix
This includes some (small) custom patches which are included in the aprinter
code. As far as I can see they are unrelated to the issue.
I have also tried to use the arm-none-eabi compiler in the Ubunutu 15.10
repositories (4.9.3) and have the same issue -
arm-none-eabi-gcc -v
