Subject: Fix: remove AC_FUNC_MALLOC from configure.ac
X-Git-Tag: v0.9.3~3
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=d5469bf4c08169f8b2d8dc136c8c350528041271;p=userspace-rcu.git

Fix: remove AC_FUNC_MALLOC from configure.ac

AC_FUNC_MALLOC fails cross-compile builds and is
only used to detect non-standard glibc behavior where
malloc(0) does not return a null pointer.

We don't depend on that behavior since we would have
to ship a compat implementation of malloc() for this
macro to be of any use.

Keep it commented because autoscan will report it
as missing and it might get re-introduced.
