Re: [Iverilog-devel] run time crash with the newest compiled version from git

[Martin W. <ic...@ma...>]

You are getting a vpiHandle to a temporary value (the evaluation of the 
expression {src1,dst2}) in the call to $put_flag and using it in your 
EndOfSimTime callback. That can't work - the temporary value only exists 
for the lifetime of the call to $put_flag.
