[Help-smalltalk] Relying on C callouts

[Lyndon Tremblay]

I am having several slighty massive hindrances relating to a design
which leverages a balanced hybrid design ST/C application. First:

$ ./iro
"Scavenging... 54% reclaimed, done.
/home/humasect/Projects/iroduke/Iroduke.st:26: Aborted
MessageNotUnderstood>>#message:receiver:
Semaphore(Object)>>#doesNotUnderstand:
[] in ProcessorScheduler>>#initialize
[] in Process>>#onBlock:at:suspend:
BlockClosure>>#on:do:
[] in Process>>#onBlock:at:suspend:
BlockContext class>>#fromClosure:parent:
Aborted.

(Line 26 being the last '!' in the file.)

I have several classes which are pure CObject derivatives. I have had
classes having instanceVariables which have needed to call
CObject>>variableWordSubclass to produce results. Is there some limit to
callouts? I can provide more code if needed; it mostly consists of
VMProxy->defineCFunc() and accompanying #defineCFunc:. Also, the GDB output:

Program received signal SIGSEGV, Segmentation fault.

Something else, the summary of Iroduke.st:

#('Class1' 'Class2' 'Class3' 'Class4' 'Class5' 'Class6' 'Class7') do:
[ :name | FileStream fileIn: 'Classes/', name, '.st' ]!

<some calls that always work>
