Of course, RC1 isn't *really* out yet, but here's a cosmetic fix.

[D​:\perl\bin]perl -we "qx​:hello.cmd​:"
assertion botched (chunk's head overwrite?)​: ovp->ovu.ovu_rmagic == 0x55555555

Can't reproduce it here.

Could you set a breakpoint at malloc.c​:assert() and give a backtrace?

I would do
sd386 perl -we "qx​:hello.cmd​:"

Opening a file is Esc t, breakpoint is F9, Run is Esc r, backtrace is Alt-F1.

Did you use -DDEBUGGING? It seems to happen only with .cmd files.

Could you set a breakpoint at malloc.c​:assert() and give a backtrace?

I would do
sd386 perl -we "qx​:hello.cmd​:"

Opening a file is Esc t, breakpoint is F9, Run is Esc r, backtrace is Alt-F1.

Sorry, no sd386. I'll *try* building an a.out perl (I had some
problems last time I tried and gave up) but it may not manifest the
bug. At least not in the same way.

Thanks. The following patch should cure this.
