There are tools such as lsstack and pstack which work on running processes,
but nothing which does core dump analysis. Does your tool already work? I
have a requirement for exactly such a tool. Any possibility of getting it?

Hi
Regarding this issue I'm woundering if anyone could give me a hint of
when Linux is using "signal trampolines"? When reading in
gdb/i386-linux-tdep.c large portion of it handles them but I can't get
the kernel to generate them. Using a simple signal handler in my
userspace test-app seems not enough.

Hi
I'm wondering if anyone can tip me with how/where to get a
minimalistic, stript gdb for doing embedded backtraces? For an embedded
project of mine I would like to insert the backtrace feature into the
system. This way it can do "self" diagnostics of app-crashes. (Only
text based logfiles are availible as feedback, can't get the binary
corefiles. Hence the analyze must be made onboard.)
Since GDB is quite big on disk and ain't suited for non-interactive
small-sized embedding I've created a backtracetool of my own. Sized to
about 12 kb it sure ain't full of features but can parse a Linux i386
corefile and show a simplified backtrace. My question is, are there any
tools available doing this already (besides gdb), or is it worth the
effort continue my work?
Best regards
