According to Patricio Domingues:

I'm trying to use signals with GPC 2.0 under Linux (binary release...).

But I have problems in assigning a function address to a pointer.

[...]

This is a known bug in GPC 2.0. Please upgrade to gpc-970510 (alpha version), available at ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/alpha/. (The next - beta - version is in preparation. Please be patient ... some days ...) Hope this helps, Peter Dipl.-Phys.
