Hi all,
I am having an immensely weird problem with newest lazarus (which was
definitely not there before).
The problem affects only code that makes use of tprocess to get output
from a shell-script and feed it back as a function result.
It is triggered whenever stdout of the main program is piped. Whether to
a file with > or to a program with |
For some reason the output from tprocess is suddenly all messed up and
ends up being random lines from my program's output.
This is rather disturbing as I have a large amount of debug info which
gets constantly dumped to stdout to allow me to track the process of the
program and identify problems with the implementation as it runs. But,
should I try to log this data with a pipe, or to seek out a specific
fragment with grep, suddenly the tprocess function gets completely
confused and I end up with random strings from my own output dumped
where the output of a shell-script is meant to be.
What could cause this ? A stack overflow in the tprocess ? Any idea
where I should look ? Was something in tprocess changed recently ?
My tprocess code is almost exactly based on the examples in the tutorial
on the lazarus wiki.
