New issue 415 by r...@cyberjunky.nl: Cannot run child process (native code)
http://code.google.com/p/gambas/issues/detail?id=415

1) Describe the problem.

While running my project from the IDE for a while it stops, and the IDE  
shows 'Cannot exec child process...' (native code)
See screenshot in attachment.

2) GIVE THE FOLLOWING INFORMATIONS (if they are appropriate):

Version: TRUNK
Revision: r5584
[System]
OperatingSystem=Linux
Kernel=2.6.38-16-generic
Architecture=x86_64
Distribution=Ubuntu 11.04
Desktop=GNOME
Theme=QGtk
Language=en_US.UTF-8
Memory=3699M

[Libraries]
GStreamer=libgstreamer-0.10.so.0.28.0
GTK+=libgtk-x11-2.0.so.0.2400.4
Poppler=libpoppler.so.13.0.0
Qt4=libQtCore.so.4.7.2
SDL=libSDL-1.2.so.0.11.3

3) Provide a little project that reproduces the bug or the crash.
Source of error is too unknown to extract the correct code yet.

4) If your project needs a database, try to provide it, or part of it.

5) Explain clearly how to reproduce the bug or the crash.
Running DomotiGa3 for a while it stops in IDE

When I connect to the hanging project with gdb you see this:

EXEC_current.pc)

(gdb)

6) By doing that carefully, you have done 50% of the bug fix job!

IMPORTANT NOTE: if you encounter several different problems or bugs, (for
example, a bug in your project, and an interpreter crash while debugging
it), please create distinct issues!
