[M3devel] compilation problems with assertions in RTCollector.m3

[Coleburn, Randy]

I updated my sandbox to be current with the HEAD branch via CVS, then tried to rebuild everything.

I first built a minimal distribution on Windows XP.  Everything seemed to work fine.

Now, using my newly rebuilt cm3.exe, I decided to rebuild everything.  Unfortunately, now I'm running into problems even in the first stage.

Here are some examples of the errors I am getting.  These runtime errors happen compiling various packages.  (I've tried rebuilding several times.)

I show 3 separate incidents below and the last one has a partial stack trace.  In each case, there is an assertion failure in the RTCollector while running the compiler:

***
*** runtime error:
***    <*ASSERT*> failed.
***    file "..\src\runtime\common\RTCollector.m3", line 1092
***

***
*** runtime error:
***    <*ASSERT*> failed.
***    file "..\src\runtime\common\RTCollector.m3", line 699
***

***
*** runtime error:
***    <*ASSERT*> failed.
***    file "..\src\runtime\common\RTCollector.m3", line 1092
***

WARNING:  Encountered an error when processing package "m3-sys\m3front" for "-build".

Any help in solving this problem would be appreciated.

Thanks,
