Oops! Sorry for the duplicate report. I'm obviously not reading the list closely enough. :( > As an aside is that "uninitialized" found by any tool/compiler? I didn't > trigger it with anything I tried. I only get the warning with gcc (v9.3.0 on Linux, and v11.2.0 on Cygwin). [clang version 10.0.0-4ubuntu1 on Linux and clang version 8.0.1 on Cygwin do not issue any warnings] Also, this particular warning depends on the level of optimization used with the command. I build with the default 'CFLAGS = -g -O2 -Wall' and with 'DEVELOPER=1'.
