Short answer:
Please just compile with -DCMAKE_BUILD_TYPE=Release to ignore the assertion.

The assertion is incorrect. It is okay to remove it. I am yet to come out with a toy example and add it as a test case.

The released binary was compiled with -DCMAKE_BUILD_TYPE=Release which will ignore all assertions. So users who use pre-compiled binaries are not affected.

@spongebob22 encountered the same issue. While it failed on the server, the assembly was successful on a local machine. I guess the binaries on the local machine was compiled with the release flag while that on the server was not.

Thanks, I'll do that.

Hello!

I am running to the same error, "exit code -6". I installed megahit using conda.

I found out that I can avoid this error when specifying just one CPU core (-t 1). But, the run takes a very long time using just one core. I would like to be able to run megahit with 10-20 cores, if possible.

I would appreciate your help.

Hello, could someone please explain to me what it means "compile with"? I don't know what I should do:
"Please just compile with -DCMAKE_BUILD_TYPE=Release to ignore the assertion."
Thank you very much

@marlaux I have the same question as you...did you ever figure out what 'compile with -DCMAKE_BUILD_TYPE=Release' meant?
