            Bug ID: 44172
           Summary: Provide a .so that overrides malloc/free with GWP-ASAN
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org
          Reporter: alex.gaynor at gmail.com
                CC: llvm-bugs at lists.llvm.org

It'd be very useful if GWP-ASAN included a .so that could trivially be
LD_PRELOAD'd to override malloc/free to use GWP-ASAN + fallback to libc's
malloc.

This would specifically make using GWP-ASAN in contexts such as
server-software, where the person doing the deployment uses OS provided
libraries such as OpenSSL or binaries like Python, and simply wants to easily
apply GWP-ASAN across their fleet.
