Details

Description: DrScheme built with --enable-noopt, causes memory leak.

Additional info:
drscheme - 4.2.3-1

Steps to reproduce:
The attached program causes mzscheme to leak memory on x86_64. I rebuilt drscheme without the --enable-noopt config option, and that version does not leak memory. As far as I can tell, the --enable-noopt flag was in the debian package descriptor, but was removed many years ago, since nobody knew why it was there. It now appears to actually be causing a problem.

The leak only appears on the x86_64 version, in the binary in the extra repository. Adding '-j' to disable JIT also prevents the leak, this seems to be some interaction between JIT, continuations and the lack of an optimizer.

Upstream binary distributions are not built with --enable-noopt.

The fix is easy, just remove '--enable-noopt' from the PKGBUILD file.

This task depends upon
