Hello, long time no see
I recently starting playing again with amxx, especially with the regex module:

#define RegexMatch(%1,%2) ( regex_match_c(%1,%2,ret) > 0 )
stock checkName(const pName[], dataCfg[structConfig], dataMatch[], &pid) {

	if(arrConfigTotalSize<1 || arrNamesSize<1)
		return false;
		
	static lpName[64], repl[64];

	copy(lpName, charsmax(lpName), pName);
	strtolower(lpName);
	
	if(containi(lpName, "replaced" )!=-1)
		return false;
	
	for (new i=0; i<arrNamesSize; i++) {
	
		ArrayGetArray(arrConfigNames, i, dataCfg);
		if(dataCfg[regexC] < REGEX_OK)
			continue;
			
		if ( RegexMatch(lpName, dataCfg[regexC]) ) {
		
			split_string(dataCfg[replacement]," ",repl,charsmax(repl));
			if(containi(lpName, repl )!=-1)
				return false;
			
			regex_substr(dataCfg[regexC], 0, dataMatch, 127);
			pid = i;
			return true;
		}
	}
	return false;
}

With this piece of code server randomly hangs, i'm testing it on both win & linux with the same amxx build 1.8.3
On windows it hangs without any error, the funny thing is if i type any char in console it will 'un'hang and everything will be fine until next random hang, on linux it will hang with this error:

PM Got a NaN velocity 2

Is there any knowing issue/problem with the regex module?
I also tested without split_string & regex_substr and the problem is the same.. so i'm suspecting regex_match_c/regex_match?
