unpack inside createColPolygon with a bad number will freeze the server and cause memory leak #4263
Description
Describe the bug
Just run this and the server will freeze and memory usage will go up and up:
tbl = split("902.82,-939.72,904.83,-939.43,905.06,-945.88,917.76,-944.39,937.67,-943.21,937.22,-940.21,930.20,-940.73929.65,-931.94", ",")
createColPolygon("902.82", "-939.72", unpack(tbl))
Notice the second to last number is a bad number: -940.73929.65
Interestingly, if the defective number is at the end of the unpack you get this:
Bad argument @ 'createColPolygon' [Expected number, got non-convertible string]
Add back the -931.94 and you get the freeze.
Steps to reproduce
srun tbl = split("902.82,-939.72,904.83,-939.43,905.06,-945.88,917.76,-944.39,937.67,-943.21,937.22,-940.21,930.20,-940.73929.65,-931.94", ",")
srun createColPolygon("902.82", "-939.72", unpack(tbl))
