[fpc-pascal]GetMem crazy problem

[Alan Mead]

Eduardo,

I did not follow your example, but are you aware of the "growing
heap" behavior of FreePascal and the ReturnNilGrowHeapFails variable?

http://www.freepascal.org/docs-html/prog/progsu113.html#x163-1680008.4

Also, I think this ReturnNilGrowHeapFails behavior is broken in 1.0.6
and fixed in 1.0.7 (which, I think, is not available yet).

But I don't know why you get RTE 201?  (You should be getting 203 or
216 or something)

-Alan

=====
A Congressman was once asked about his attitude toward whiskey.  "If you mean the demon drink that poisons the mind, pollutes the body, desecrates family life, and inflames sinners, then I'm against it. "

"But if you mean the elixir of Christmas cheer, the shield against winter chill, the taxable potion that puts needed funds into public coffers to comfort little crippled children, then I'm for it."
 
"This is my position, and I will not compromise."
