Hi!
quoted
There is a problem with the stack size accounting during execve when there is no stack limit: $ ulimit -s 8192 $ ./hello.ilp32 Hello World! $ ulimit -s unlimited $ ./hello.ilp32 Segmentation fault $ strace ./hello.ilp32 execve("./hello.ilp32", ["./hello.ilp32"], 0xfffff10548f0 /* 77 vars */) = -1 ENOMEM (Cannot allocate memory)+++ killed by SIGSEGV +++Segmentation fault (core dumped) Andreas.Thanks Andreas, I will take a look. Do we have such test in LTP?
We do have a test that we can run a binary with very small stack size i.e. 512kB but there does not seem to be anything that would catch this specific problem. Can you please open an issue and describe how to reproduce the problem at our github tracker: https://github.com/linux-test-project/ltp/issues Then we can create testcase based on that reproducer later on. -- Cyril Hrubis chrubis@suse.cz
