Dockerfile-asan-test

# Dockerfile for reproducing the ASAN ODR violation (GitHub Issue #1632)
#
# This builds PHP from source with AddressSanitizer enabled, then builds
# both sqlsrv and pdo_sqlsrv extensions and attempts to load them together.
#
# Usage:
#   docker build -f Dockerfile-asan-test -t msphpsql-asan-test .
#   docker run --rm msphpsql-asan-test
#
# Expected results:
#   BEFORE fix: ASAN aborts with "odr-violation" on g_sqlsrv_stream_wrapper / isVistaOrGreater
#   AFTER fix:  php -v succeeds, both extensions load cleanly
