Bug ID: 90471
Summary: ICE Segmentation fault when compiling with debug info
Product: gcc
Version: 7.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org

Preprocessed code
I got ICE Segmentation fault when trying to build OpenCL BOINC app which I am
developing. This happen only when I use -g option, without it code compiles
fine.
I compiled code using MinGW crossompiler shipped with Cygwin. Exact versions of
all mingw packages are on attached screen. I also attached preprocessed source.
I use 64-bit Cygwin on 64-bit Win 10 Pro with latest patches.
When I was trying to remove unimportant parts of source code, I found
interesting thing: I was able to comment out boinc_opencl.h include and crash
still happen. However when I removed this line completely, gcc did not crash.
This part of code looks as follows:
[code]
#define __CL_ENABLE_EXCEPTIONS
#define CL_TARGET_OPENCL_VERSION 120
#define CL_USE_DEPRECATED_OPENCL_1_1_APIS
#include "CL/cl.hpp"
//#include "boinc_opencl.h"
class OclException : public std::exception
[/code]
I can attach original files and all relevant headers if you need them too.
