the recovery of the functions variable was missing in a case of missing graph
file

it seems like the author of the code intended to set the functions variable in
case of a failure, and saved the original into old_functions, but forgot to
actually do it in case there are no graph file to the currently processed .c
file.

[Bug c++/43321] New: [c++0x] ICE on valid auto

2010-03-10 Thread adam dot rak at streamnovation dot com 
I hope it's a valid auto. the code works if I write int instead of auto.

It might be related to Bug 43281

internal compiler error: in type_unification_real, at cp/pt.c:13486

template typename T 
void shuffle(const T first, const T last)
{
auto w = *first;
}

int main()
{
  int b[5];
  shuffle(b[0],b[4]);
}

[Bug c++/43281] New: [c++0x] ICE in nested lambda functions, in a special case

2010-03-07 Thread adam dot rak at streamnovation dot com 
it resembles Bug 41896 but with the addition of line: auto val = val;

The code is legal but doesn't make any sense. In some rare cases which I
couldn't replicate simply, it went into an infinite mallo, consuming the whole
memory, instead of segfault.

float nested_lambda()
{
float val;

[val]()
{
auto val = val;
[val]()
{
};
};
}

[Bug c++/41896] New: [cxx0x-lambda] Segfault because of a nested lambda function

2009-11-01 Thread adam dot rak at streamnovation dot com 
Code for triggering the BUG:

float nested_lambda()
{
float val;

[val]()
{
[val]()
{
}
}
}

 float nested_lambda() nested_lambda()::lambda()
stdin:7:4: internal compiler error: Szegmens hiba
Please submit a full bug report,
with preprocessed source if appropriate.
See http://gcc.gnu.org/bugs.html for instructions.

according to gdb, the segfault originates at: cp/semantics.c:2814, and it's a
null pointer dereferencing. After a bit of inspection, it was revealed that in
the code:

decl = add_default_capture (lambda_stack,

llambda_stack is NULL.

I tried the code:
float nested_lambda()
{
float val;

[val]()
{
float val2 = val;
[val2]()
{
}
}
}

which seems to be working fine.
