+description = """I found Qemu shows different behavior when I run Qemu with hello-world (statically linked binary enclosed) directly or run it through remote debugger. I need help to understand the following: 
+
+1. Is this intended behavior?
+1. Any way to make the two approaches have consistent behavior (I prefer the behavior shown in the 2nd approach described below)
+1. If it is intended behavior, any explanation why or suggestions how to dig further to root cause the difference.
+
+The corresponding source code is the line 86 in [filedoalloc.c](https://code.woboq.org/userspace/glibc/libio/filedoalloc.c.html#86). It tests if the file (stdout) is char special device (S_ISCHR)
+The preprocessed code is as follows:
+   if (((((st.st_mode)) & 0170000) == (0020000))) 
+
+I then compared two different approaches to run Qemu:
+
+1. I used the following command line to collect the trace:  qemu_aarch64 -strace  -plugin $QEMU_ROOT/build/contrib/plugins/libexeclog.so -d plugin hello.a64. This one tests False for S_ISCHR
+1. when I used gdb to connect to Qemu and single-step the instructions, S_ISCHR tests True, which is different from running qemu directly (approach 1).

+Thanks!"""
