Hexagon tools: command line too long

I have been working with Hexagon SDK 3.5.1 and tools version 8.3.07.  I have made some emulator tests for Linux, and all is fine - except now that I added a test with a very long command line. On Linux (Ubuntu 20.04 x86_64 ) I am running

hexagon-sim "--pmu_statsfile" "/dev/null" "-mv65" "--simulated_returnval" "--"  foo -arg1 LOOONGLINE -arg2 LOOONGLINE -arg3 LOOONGLINE  

where the resulting line is above 1200 characters.

I see

28: hexagon-sim INFO: The rev_id used in the simulation is 0x00004065 (v65a_512)
28: hexagon-sim WARNING: sim_handle_trap in src/hexswi.c:1790: Cmdline too long
 
It seems that I have ~1183 characters as the maximum line length.
Is there a way to circumvent this limitation? Some environment variable to set?

Same problem exists for SDK 3.0 with tools 7.2.10-1-r2

Do any Qualcomm develop ever look at these posts?
