gcc segmentation fault (signal 11 ) while compiling brotli on Cygwin AppVeyor CI i686 environment

cygwin-apps mailing list
Hi!

I'm preparing brotli-1.0.9-1 packages, which are successfully built and packaged on my local machine.

Being tested on Cygwin AppVeyor CI, it goes successfully on x86_64,
but it fails on i686 because gcc gets a signal 11.

Differnce of the cygport files is just a line `uname -a` in src_compile(), so we would expect failures at same point.
But failure points are diffent.

In 1056, it fails at 'gcc ... -c python/_brotli.cc -o bin/temp.cygwin-3.1.7-i686-2.7/python/_brotli.o'
 https://ci.appveyor.com/project/cygwin/scallywag/builds/35671931/job/rro6vjdefpxyen3c

In 1055, it fails at 'gcc ... -c c/common/constants.c -o bin/temp.cygwin-3.1.7-i686-2.7/c/common/constants.o'
 https://ci.appveyor.com/project/cygwin/scallywag/builds/35671826/job/6cijsycw1n7qmumr



Currently, I have no idea how to solve this issue.

Although similar issue was reported in the past
  https://sourceware.org/legacy-ml/cygwin/2014-10/msg00552.html ,
there seems no essential solution found.



Because the packages have been built successfully on my local environment,
Can I ignore this failure?



Any help is welcome.
Thank you in advance.

Regards,

Lem

I've had this problem with several of my packages.

That's what I've done.
