Hi,
I’m seeing the occasional but reproducible crash using a lefse command like this:
mothur > lefse(shared=current, design=abc123.design)
Using abc123.shared as input file for the shared parameter.You did not provide a class, using abc123.
0.03
Number of significantly discriminative features: 23 ( 81 ) before internal wilcoxon.
*** Error in `mothur’: free(): invalid pointer: 0x0000000001e4dcd0 ***
Aborted
The crash can be triggered with certain combinations of input data and seed parameter (as in set.seed() ) and whether or not I run mothur under gdb. So in practice I can avoid the crash by trying different seed parameters but when I run a batch, say, containing twenty or so lefse commands, among others, crashes become rather likely. This happens with the non-MPI Linux 1.36.1 mothur version, the downloaded pre-compiled one as well the binary Debian version. Mothur 1.33.3 as shipped by Debian jessie is also affected. The following stack-trace was made with mothur 1.36.1 Debian source package re-compiled with -Og -g flags, I hope that helps:
*** Error in `/home/$USER/src/mothur-1.36.1/mothur’: free(): invalid pointer: 0x0000000001bc4400 ***
