Line 455 is currently `M2errorRegexp := "^[^:\n]+:[0-9]+:[0-9]+:(\\([0-9]+\\)):\\[[0-9]+\\]: "` It should probably say `M2errorRegexp := "^[^:\n]+:[0-9]+:[0-9]+:(\\([0-9]+\\)): "` This fixes an issue where check(Package) doesn't report the actual errors in tests.

Under Mac OS I've seen GC_MAXIMUM_HEAP_SIZE=400M get rejected as a bad value, and then M2 can't start, because there is not enough memory (?). The users had our binary distribution,...
Despite the fact that submatrix makes a copy of mutable matrices, hash of the two objects stays the same. ``` i1 : A = mutableMatrix {{10}} o1 = | 10...
After 10 or 20 example failures, `installPackage` should give up. One reason is that core dump files may be created, and they are large.
After running `make`, running `make install` should not rebuild anything.
