differently so the problem did not occur? If you still have that version
installed, can you compare the -S output of the previous and the current
GPC version to see what's different? (Just to be sure it really isn't a
code generation problem...)
I re-installed the previous version exactly as I had it before with
GCC 2.7.2.1 and everything, but could not reproduce the error! It's a
miracle that it never crashed before.. There is one thing tho, it seems
that variables declared within the program are not properly exported
outside of the source module. I attatched a simple example program to show
what I mean. 

See ya!
