csi from git version: slow?

Hello, I've tried the git version (2024-02-23, compiled with LLVM-17 
clang, on a Debian 12 / linux 6.6.x). While csc and the executables it 
generates are a bit faster, running my program under csi is now twice as 
slow compared to the latest release (5.3.0).


Now before I engage in other investigations, like compiling with GCC, 
checking the nature of my program (sets a large number of globals by 
running some DSL-type macros hundreds of times, would be the most 
obvious distinguishing characteristic), I need to ask this first: is 
this to be expected? Are there some "development version" / debug flags 
/ expensive interpreter features that differ compared to stable? I 
customized only config.make by changing the C_COMPILER and PREFIX.


Thanks, Al
