Dear Nick,
Will my replacing fix-stacks binary with a binary to echo the input line
verbatim into the output
help me to obtain the original stack trace line?
I need to get the ORIGINAL line to see if I can get my interim script
based on linux-stack-fix.py to work
and understand the subtle issue about the base address mentioned in the
github ticket.
Obviously the offset printed in the current log against split debug
executable cannot be fed to the original linux-stack-fix.py to obtain
reasonable
stacktrace from my experiment. I thought it was OK, but it was pointed
out that the stack trace thus obtained was trash.
(See https://bugzilla.mozilla.org/show_bug.cgi?id=1621274 )
Strange. linux-stack-fix.py used to work when the output was not
modified by the recent fix-stack. That is what I used to
for many years.
TIA

Thank you for the tips.
I will have a go to incorporate the logic of old fix_linux_stack.py
into fix-stacks.
TIA

Ouch, I am using -gsplit-dwarf to make gdb startup time faster...
-gsplit-dwarf is set manually on my bash script before invoking ./mach
configure and build.
That would be the problem!
Do you think digging github of fix-stack gets me anywhere near the
solution?
Or do I have to do a major surgery in the innards of|used libraries of
symbolic and/or goblin ?
https://github.com/mozilla/fix-stacks/issues/22 is the open issue for
separate debug info. There is some information in that issue about
what is
necessary. I think copying over the old logic from fix_linux_stack.py
would
be a moderate-sized task.
