Hi,
I'm using Buildr, a build tool based on Ruby. I have compiled the Ruby
implementation on my computer which is Ubuntu 8.04.
I'm getting SIGSEGV, when running the program. Looking at the source
code the fault happens at a line that contains only an opening curly
brace for a function. There are 703 function calls in the stack, but
the stack size is unlimited (ulimit -s)
What is the cause of this fault (assuming that faulting on a curly
brace is some phenomena that is not related directly to bugs in the
code)? Is there a work around?
Thank you,
Ittay |

Is the crash happening in the main thread, or in some other thread?
There is no such thing as unlimited stack size for threads other
than main, and it's possible to run out of stack even in the
main thread.
703-deep recursion sounds excessive. Is it infinite?
You can tell whether you ran out of stack with gdb 'x/20x $esp'
command. If gdb says "unable to access memory at (no spam) ...", then you have.
If stack is accessible, what is the output from 'x/10i $pc-15' and
'info reg'?

You have the program crashing under debugger control; we don't.
You tell us.
