In trunk, (ccl::choose-file-dialog) sometimes works, but opening a directory then selecting a file causes CCL to crash. This in 1.6-dev-r14201M-trunk, this bug seems to be absent in 1.5-rc1-r13620M. Exception Type: EXC_BAD_ACCESS (SIGSEGV)

The trunk version of Clozure CL kernel crashes on Ubuntu 10.04 (​Linux kernel 2.6.32-24.41).

On ​Linux kernel 2.6.32-23.37, it works fine.

When compiling the kernel with mingw-w64 + cygwin + win7-64bit (mingw-w64-bin_i686-cygwin-1.7.6-1_20100902, cygwin 1.7.7), lots of "undefined reference" errors will be emitted. Removing "define(CNamesNeedUnderscores',')" from "ifdef(`WINDOWS'...)" in m4macros.m4 will solve the problem.
