Arch Linux

Description:

When we try to cross compile for an arm chip we run into an internal compiler error. We think there is an link to an virtual function. We use the following parameters:
/usr/bin/arm-none-eabi-g++ -I[..] -I[..] -mcpu=arm926ej-s -mthumb-interwork -mfloat-abi=soft -mlittle-endian -mapcs-frame -mlong-calls -marm -mtune=arm926ej-s -nostdinc -nostdinc++ -std=c++98 -fno-exceptions -ffunction-sections -fdata-sections -fno-rtti -funsigned-char -Wall -Wextra -pedantic -Wformat -Winit-self -Wfloat-equal -Wclobbered -Wempty-body -Wignored-qualifiers -Wmissing-field-initializers -Wsign-compare -Wtype-limits -Wuninitialized -Wshadow -Wcast-qual -Wredundant-decls -Wmissing-declarations -Wlogical-op -Wsign-conversion -Wwrite-strings -Wundef -Wunused-parameter -Wno-vla -Wno-long-long -Wno-unknown-pragmas -Wconversion -std=c++98 -fno-exceptions -ffunction-sections -fdata-sections -fno-rtti -funsigned-char -Wall -Wextra -pedantic -Wformat -Winit-self -Wfloat-equal -Wclobbered -Wempty-body -Wignored-qualifiers -Wmissing-field-initializers -Wsign-compare -Wtype-limits -Wuninitialized -Wshadow -Wcast-qual -Wredundant-decls -Wmissing-declarations -Wlogical-op -Wsign-conversion -Wwrite-strings -Wundef -Wunused-parameter -Wno-vla -Wno-long-long -Wno-unknown-pragmas -Wconversion -O2 -o CMakeFiles/Start_objs.dir/start/CodeFile.cpp.obj -c /home/[..]/CodeFile.cpp
/home/[..]/CodeFile.cpp: In member function 'virtual void NameSpace::Test::_ZThn8_N6Safari18CodeFile16OnTimerActionEP7TMR(TMR*)':
/home/[..]/CodeFile.cpp:70:1: internal compiler error: in gen_reg_rtx, at emit-rtl.c:1026
} /* NameSpace */

We are able to Compile the same Code with Windows and Code Sourcery 4.5.2

Additional info:
* package version [arm-none-eabi-gcc] 7.3.0-1
* there is no special configuration made


Steps to reproduce:

Compile C++ Code with wirtual functions for a arm V9 architecture arm926ej-s

Please write if you need additional information. If necessary i will create an minimal example where the error occours.
