[Chicken-users] Using -accumulate-profile

Hi there, I'm building a program with csc and it's running slower than I'd hoped so I'm trying to do some profiling. I tried using the -accumulate-profile option to concatenate information from multiple runs of the program but it seems to produce the same result as just using -profile (i.e. multiple PROFILE.<pid> files, each containing information from a single run). I thought maybe I had to explicitly set the profile file name using -profile-name but that doesn't help (it changes the stem (i.e. <name>.<pid> with -profile-name <name>) but still multiple executions create multiple files). I'm using 4.6.3 on 64-bit Linux: "linux-unix-gnu-x86-64 [ 64bit manyargs dload ptables ]". I had thought from reading the doc that using -accumulate-profile would build up a single profile output file containing information for numerous successive executions; is that not correct? Thanks for any advice (pointers to any general tips on profiling and optimizing in Chicken also greatly appreciated).
