Bug ID: 113183
Summary: LTO crashes with Segmentation fault
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: sebunger44 at gmail dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---

Contains the LD and CPP files
I'm in the process of creating a tool-chain and porting FreeRTOS to our Leon2
based platform and ran into this with GCC 13.2. However, after reducing it to a
near trivial example, I can now also reproduce it on GCC 11.4 as shipped by
Ubuntu 22.04. So it probably has nothing to do with how I compiled my GCC etc.
Output:
$ gcc -nostartfiles -O2 -flto -T link.ld tt.cpp -o tt

lto-wrapper: fatal error: gcc returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status
Note that I do not expect this example to run in any way. I have cut out all
the target specific stuff so only plain old C++ remained.
