5.0.2 extension for php 7.4 zts compiled as non-zts

[glensc]

PHP Warning:  PHP Startup: Unable to load dynamic library '/tideways_xhprof-7.4-zts.so' (tried: /tideways_xhprof-7.4-zts.so (/tideways_xhprof-7.4-zts.so: undefined symbol: compiler_globals), /usr/local/lib/php/extensions/no-debug-zts-20190902//tideways_xhprof-7.4-zts.so.so (/usr/local/lib/php/extensions/no-debug-zts-20190902//tideways_xhprof-7.4-zts.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

The undefined symbol: compiler_globals indicates that extension was compiled NTS but attempted to be loaded as ZTS.

I discovered this fault when attempted to use your extension in Travis CI:

here's a script that tests all versions via docker images. integrate in your qa.

 #!/bin/sh

set -eu
for m in $(seq 0 4); do
	v=7.$m

	ext=tideways_xhprof-$v.so
	local=$(pwd)/tideways_xhprof-5.0.2/$ext
	if test -f $local; then
		docker run --rm \
			-v $local:/tideways_xhprof-$v.so \
			php:$v-cli \
			php -dextension=/tideways_xhprof-$v.so -r 'printf("- %s (%s): %s\n", PHP_VERSION, PHP_ZTS ? "ZTS": "NTS", var_export(extension_loaded("tideways_xhprof"), 1));'
	fi

	ext=tideways_xhprof-$v-zts.so
	local=$(pwd)/tideways_xhprof-5.0.2/$ext
	if test -f $local; then
		docker run --rm \
			-v $local:/$ext \
			php:$v-zts \
			php -dextension=/$ext -r 'printf("- %s (%s): %s\n", PHP_VERSION, PHP_ZTS ? "ZTS": "NTS", var_export(extension_loaded("tideways_xhprof"), 1));'
	fi
done

also, do you know that your download is lacking 7.0-zts extension?
