Bug ID: 93758
Summary: Building x86_64-w64-mingw32-gcc (mingw-w64) on macOS
Catalina results in "internal compiler error:
Segmentation fault"
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: mojca at macports dot org
Target Milestone: ---
See:
* https://trac.macports.org/ticket/60091
* https://ports.macports.org/port/i686-w64-mingw32-gcc-nothreads/builds
Since macOS Catalina (10.5) we are apparently no longer able to build
x86_64-w64-mingw32-gcc.
Bootstrapping (make all-gcc && make install-gcc) is performed with clang and
succeeds (but I'm not excluding the chance that there is a bug in the clang
compiler as shipped on Catalina; we had numerous issues which required using
-fno-stack-check).
