Description of problem:
Segfault while compiling pcsx2

gcc segfaults while compiling pcsx2 (git version 56a976e277a4a05622bd6396d8ee9049b62049cd)

The command line is:

How reproducible:

Always

Steps to Reproduce:
1. Try to compile the file

The file compiles (I did not have problems with the compiler of f29)

Additional info:
 I include the preprocessed file;

Comment 1 Jakub Jelinek 2019-05-01 18:03:11 UTC
Why are the sources using fastcall attribute?  Especially using templates on function types with that attribute makes no sense at all on Linux.

Comment 2 Luca Giuzzi 2019-05-01 18:33:25 UTC
Honestly, I have no idea about the reason for the fastcall attribute. I shall open a bug report upstream.
In any case, if I disable the attribute where it is used, then the compilation ends without problems and also the program appears to run.
The code is x86-32 and not x86-64

None the less, it is weird that the compiler fails with a segmentation fault.

Comment 3 Luca Giuzzi 2019-05-01 18:42:10 UTC
Incidentally, if I remove the __fastcall attribute, then the relevant code path fails (it is a software fallback for when there is no hw rasterizer)...

Comment 4 Fedora Update System 2019-05-04 13:01:10 UTC
gcc-9.1.1-1.fc30 has been submitted as an update to Fedora 30. https://bodhi.fedoraproject.org/updates/FEDORA-2019-007851f216

Comment 6 Luca Giuzzi 2019-05-05 10:23:07 UTC
I confirm that gcc-9.1.1-1.fc30 from updates-testing seems to fix the problem (the code compiles without segfaulting the compiler and also it appears to work properly).

Comment 7 Fedora Update System 2019-05-07 05:41:41 UTC
