[M3devel] PPC_LINUX hangs in m3_strtod? and an assertion failure

[Jay K]

I'm seeing wierd stuff.
 
On PPC_LINUX.
 
Compiling some files hangs.
Such as M3Front.m3.
 
It is actually looping forever in 
 
Breakpoint 1, m3_strtod (s00=0x7feb9ef0 "4.9406564584124654e-324")
 
 
which, you know, other than feeding it bad data, or corrupting
its stack when it calls out to our lock/unlock, we can't mess up.
 
 
I can watch what strings it gets on other systems and/or make
a standalone case that hangs.
 
 
While investigating this I hit control-c on a cm3 and hit:
 
 
new source -> compiling SchedulerPosix.i3   (hung here)

***
*** runtime error:
***     failed.
***    file "..\src\runtime\common\RTCollector.m3", line 1087
***
Aborted
 


PROCEDURE CleanBetween (h, he: RefHeader; clean: BOOLEAN) =
  BEGIN
    WHILE h < he DO
      
         line 1087
 
 
Maybe we don't deal with control-c at arbitrary points??
 
 
I was able to reproduce this assertion failure twice in a row..
though it moved to line 1089 the second time.
 
 
 
PROCEDURE CleanBetween (h, he: RefHeader; clean: BOOLEAN) =
  BEGIN
    WHILE h < he DO
      
      
      IF h.gray THEN
             line 1089
 
 
I verified that the hang compiling SchedulerPosix.i3 is also related to floating point conversion.
This time in m3_dtoa.
 
 
I will look further.
Maybe my config file changes..but seems odd..
