The error is triggered randomly by almost all .png and only when I use
more than one job.
Doing "doc -rf doc/" before compiling doesn't seem to prevent the error.
Here is another case
GEN doc/interpreter/interpderiv1.png
error: imwrite: invalid empty image
error: called from
__imwrite__ at line 34 column 5
imwrite at line 119 column 5
