Re: [Bug-apl] 2 Defects in 81x

[Juergen Sauermann]

Hi Fred,

thanks, hopefully fixed in SVN 820.

Please note that there are definitely some faults (lock-ups) remaining if parallel execution
is enabled. These faults were sporadic and difficult to reproduce.
 My benchmarks of parallel execution did not show significant benefits on
today's CPUs and therefore I have not yet taken the time to find these faults.

Two defects to report.

I use GNU APL as libapl from another application (not lua). I also use
parallel.

Defect 1:

In libapl.cc, function Unicode_to_UTF8(), the memcpy() second argument
is &utf8.at(0) This is not correct with the current Simple_string.hh

Easiest fix is to remove the "protected:" line in Simple_string.hh

Defect 2:

In Parallel.cc, there is a call all_CPUs.resize(count). With the current
Simple_string.hh this does not work.

Easiest fix is to change to all_CPUs.shrink(count)
