According to Olivier Lecarme:

Following the indications in the GPC manual, I tried sending a bug report to bug-gpc@prep.ai.mit.edu, which does not exist. As a last resort, I'm trying the GPC mailing list, hoping it exists!

It does exist. :-)

----- The following addresses had permanent fatal errors ----- bug-gpc@prep.ai.mit.edu (expanded from: bug-gpc@prep.ai.mit.edu)

In fact we have a bug reporting system: See the page "bugs" on our WWW site,

http://home.pages.de/~gnu-pascal/

but actually most bug reports go through this list, so you did it right. I expect that the mail reporting system will become more useful when GPC is getting more stable and we will fine-tune the compiler.

I get the following message when compiling a somewhat complicated program (2352 lines):

gpc: Internal compiler error: program gpc1 got fatal signal 6

What can I do? Send you the whole program would probably be useless. Are there some options I could trigger in order to get more information?

Alpha versions of GPC have an option "-dY" which tells GPC to echo each source line to stderr. Then you can see where in the source GPC crashes.

Another interesting option in this context is "-dy" which lets GPC output parsing debugging information. If you post the last "rule" listed there, e.g.

Reducing via rule 616 (line 3782), variable_or_function_access_maybe_assignment rest_of_statement -> assignment_or_call_statement

it might already tell me something about the error. (The line number refers to the GPC source file `gpc-parse.y'.)

By the way, I encountered another problem with GPC: one program writes a file of some complicated record type; another program reads this file, declared in exactly the same way. However, it seems that every get(file) skips to the next *physical* record, instead of the next logical one.

This I don't understand ... could you please explain what you mean by "physical" and "logical"?

Perhaps it's an alignment problem? Within records, GPC aligns Integers on 4-byte boundaries, etc.
