gcc segfault on cygwin 2.3.1-1 with aircrack-ng svn r2719


Hi,

I just updated to cygwin 2.3.1-1 after https://cygwin.com/ml/cygwin/2015-11/msg00186.html1 to see if the update solves the issue but it still segfaults. I only tested gcc 5.2.0-1 and I'm pretty sure it's gonna happen on every other gcc version available since the output is exactly the same as on 2.3.0:

$ make
make -C src all
make[1]: Entering directory '/home/Thomas/aircrack-ng-trunk/src'
gcc -g -W -Wall -O3 -D_FILE_OFFSET_BITS=64 -D_REVISION=2719 -DCYGWIN -fstack-protector-strong -Wno-unused-but-set-variable -Wno-array-bounds -Iinclude -c -o aircrack-ng.o aircrack-ng.c
gcc: internal compiler error: Segmentation fault (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Here is gcc info (5.2):
$ gcc -v

I'm attaching 'cygcheck -s -v -r' output to this email.

Since I remembered it still worked with 2.2.1 on this computer, I tried to compile it on another computer I hadn't updated and compilation worked as expected.

Let me know if there is any more information needed to help you debug the issue.

Best regards,

Thomas
