Possible bug in LocalProcess [message #47665]

Hi,
using LocalProcess I got a bug which makes it work only FIRST time it's called, then fail.
Dumping 'args' variable in LocalProcess::DoStart() gives following :

args = [/home/massimo/.FishIDE/packages/fishino/tools/pic32-tools/4.8.3-pic32gcc/bin/pic32-gcc, .....

on first call, and

args = [FreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFreeFree@, -c, -g, .....

on next calls.
Adding an args.Clear() at beginning of the function solves the problem :

bool LocalProcess::DoStart(const char *command, const Vector<String> *arg, bool spliterr, const char *envptr)
{
	LLOG("LocalProcess::Start(\"" << command << "\")");
	args.Clear();  <=== HERE!
	Kill();

here the dumps :

args = [/home/massimo/.FishIDE/packages/fishino/tools/pic32-tools/4.8.3-pic32gcc/bin/pic32-gcc, -c, -g, -Os..... (first call)

args = [/home/massimo/.FishIDE/packages/fishino/tools/pic32-tools/4.8.3-pic32gcc/bin/pic32-gcc, -c, -g, -Os..... (second call)

Ciao

Massimo

Another problem : on second run (and following...) it will not gather error/output from process.
This seems solved adding an Init() along the former args.Clear():

bool LocalProcess::DoStart(const char *command, const Vector<String> *arg, bool spliterr, const char *envptr)
{
	LLOG("LocalProcess::Start(\"" << command << "\")");
	Kill();
args.Clear();   <==== HERE
Init();         <==== HERE

That's weird, I was using localprocess before and it did work. Maybe some changes ?

Hi,

sorry for the bug, I guess nobody used LocalProcess second time yet. But it has to work obviously.

I have used different way to fix the issue, because calling Init clears all features of LocalProcess (e.g. ConvertCharset flag). I have also added reusing LocalProcess to autotest.
