17.10 failed with a similar message to: http://patchwork.ozlabs.org/patch/772848/ but applying that patch did not solve it, apparently there were fixes already on later versions of the tracked package. Update .gitmodules to ignore patches we apply to Buildroot.

Subject: [PATCH] flex: Fix segfault of stage1flex when host has glibc 2.26 or
|
|
newer
|
|
|
|
When the host uses glibc 2.26 or newer, Flex will try to use the
|
|
newly-introduced reallocarray() function, but as it would not define
|
|
_GNU_SOURCE a segmentation fault would occur later on due to the
|
|
compiler assumming that the function is implicitly defined.
|
|
|
|
This issue manifests itself due to a crash of "stage1flex" during the
|
|
Flex bootstrap:
|
|
|
|
./stage1flex -o stage1scan.c ./scan.l
|
|
make[2]: *** [Makefile:1725: stage1scan.c] Segmentation fault (core dumped)
|
|
|
|
This imports the patch from the upstream Git repository, and adds flags
|
|
in the .mk file to rebuild the Autotools scripts and support files. Due
|
|
to the latter, the patch to disable the documentation is changed so it
|
|
modifies the .am file instead.

|

|
|
+This would, e.g. define _GNU_SOURCE in config.h, enabling the
|
|
+reallocarray() prototype in glibc 2.26+ on Linux systems with that
|
|
+version of glibc.
|
|
+
|
|
+Fixes #241.
