Hello everyone,

I am trying to inject faults into c files with the help of coccinelle spatch.
I ran into this problem that the benchmarking framework that I am using, runs the tools (coccinelle) in a containerized environment with READ_ONLY permissions to the input file's directory.
The issue is that when running the command (within the container):
spatch template.cocci example.c -o /target
It writes the output not only in the desired target directory but also in the same directory as the input files which is leading to permission issues.

is there a way to change that behaviour of spatch? and to create the output only in the desired target directory?
this is the output.txt that I get:

cat cvt-output/coccinelle-default/3cb48d4b-12bb-41bc-85b0-23c1f3f28a48/output.txt 
/usr/local/bin/spatch ../../../tmp/program.c ../../../tmp/template.cocci

Thanks for the report. I can't reproduce this issue. If you are still having problems with this, could you provide reproducible steps?
