Hi 
script code:
// Global scope
Object @obj = CraeteObject();
// C++
Object *CreateObject()
{
asIScriptContext *ctx = asGetActiveContext();
assert( ctx );
int stack_size = ctx->GetCallstackSize();
if( stack_size > 0 )
{
const char *script_section;
int line = ctx->GetLineNumber(0, 0, &script_section); // Crash
}
}
I couldn't recreate the problem. I believe this has already been fixed in the latest revision.
Could you try the latest revision and let me know if the problem still happens for you?
Hi egane)
in revision 1564 - problem resolved itself
I made ??a mistake - Its not true!
I couldn't recreate the problem. I believe this has already been fixed in the latest revision.

I had to strain to find it)
So! Bug show, if we use empty file, but not empty as this "" - emty as that " // not use source"!
for reproducte bug, you a need use two files!
First file:
Text @a = scene.Cr();
Second file:
// file with out work body!
Scene::Cr
void *Scene::Cr()
{
asIScriptContext *ctx = asGetActiveContext();
const char *script_section;
int line = ctx->GetLineNumber(0, 0, &script_section);
return nullptr;
}
Thanks. I'll try again with this additional information.
May I ask how on earth you're coming up with all these odd scenarios? 
I'm sorry, but I still can't reproduce the problem.
I wrote the following test based on what you provided:
class TestLN
{
public:
void *TestLineNumber()
{
asIScriptContext *ctx = asGetActiveContext();
const char *script_section;
int line = ctx->GetLineNumber(0, 0, &script_section);
return 0;
}
};
bool Test()
{
bool fail = false;
// Test crash in GetLineNumber
// http://www.gamedev.net/topic/638656-crash-in-ctx-getlinenumber/
{
asIScriptEngine *engine = asCreateScriptEngine(ANGELSCRIPT_VERSION);
engine->RegisterInterface("foo");
engine->RegisterObjectType("Test", 0, asOBJ_REF | asOBJ_NOCOUNT);
engine->RegisterObjectMethod("Test", "foo @TestLineNumber()", asMETHOD(TestLN, TestLineNumber), asCALL_THISCALL);
TestLN t;
engine->RegisterGlobalProperty("Test test", &t);
asIScriptModule *mod = engine->GetModule("test", asGM_ALWAYS_CREATE);
mod->AddScriptSection("a","foo @f = test.TestLineNumber();");
mod->AddScriptSection("b"," // nothing to compile");
int r = mod->Build();
if( r < 0 )
TEST_FAILED;
engine->Release();
}
return fail;
}
What do I need to change to reproduce the crash?

my engine can use multiply tabs, and any tab use asIScritpEngine. If exemple i open 5 tabs in debug mode, script compilation time ~2300 msec ( 5 tabs is over 10 second ), I all time use save and load byte code 
Problem show after save and load byte code, use can use this exemple:
class CBytecodeStream : public asIBinaryStream
{
public:
CBytecodeStream() {wpointer = 0;rpointer = 0;}
void Write(const void *ptr, asUINT size)
{
if( size == 0 )
return;
buffer.resize(buffer.size() + size);
memcpy(&buffer[wpointer], ptr, size);
wpointer += size;
}
void Read(void *ptr, asUINT size)
{
memcpy(ptr, &buffer[rpointer], size);
rpointer += size;
}
int rpointer;
int wpointer;
std::vector<asBYTE> buffer;
} script_stream;
class TestLN
{
public:
void *TestLineNumber()
{
asIScriptContext *ctx = asGetActiveContext();
const char *script_section;
int line = ctx->GetLineNumber(0, 0, &script_section);
return 0;
}
};
void Reg( asIScriptEngine *engine ){
engine->RegisterInterface("foo");
engine->RegisterObjectType("Test", 0, asOBJ_REF | asOBJ_NOCOUNT);
engine->RegisterObjectMethod("Test", "foo @TestLineNumber()", asMETHOD(TestLN, TestLineNumber), asCALL_THISCALL);
TestLN t;
engine->RegisterGlobalProperty("Test test", &t);
}
bool Test()
{
bool fail = false;
// Test crash in GetLineNumber
// http://www.gamedev.net/topic/638656-crash-in-ctx-getlinenumber/
{
asIScriptEngine *engine = asCreateScriptEngine(ANGELSCRIPT_VERSION);
Reg( engine );
asIScriptModule *mod = engine->GetModule("test", asGM_ALWAYS_CREATE);
mod->AddScriptSection("b"," // nothing to compile");
mod->AddScriptSection("a","foo @f = test.TestLineNumber();");
int r = mod->Build();
script_stream.wpointer = 0;
mod->SaveByteCode( &script_stream );
asIScriptEngine *engine2 = asCreateScriptEngine(ANGELSCRIPT_VERSION);
asIScriptModule *mod2 = engine2->GetModule(0, asGM_ALWAYS_CREATE );
Reg( engine2 );
script_stream.rpointer = 0;
mod2->LoadByteCode( &script_stream );
assert( r >= 0 );
engine->Release();
}
return fail;
}
I'm wondering about that as well
