(4) compiling any .c source with -ggdb or -gdwarf-2 (instead of -gstabs or -g) produces the following output: Internal compiler error in default_no_named_section, at varasm.c:5305

Darwin doesn't really support dwarf2 at present.

Fixed with gcc-3.3, there is now a message "unknown or unsupported -g option". Geoff Keating wrote:

Does anyone know what the status is of the following problems, encountered with gcc-3.2.1/3.2.2 on Darwin/Mac OS X ?

(1) trampolines crash (I have a patch to fix it)

(2) longjumps crash (I have a patch to fix it also)

(3) non-local goto's don't work, e.g.

These are all fixed in GCC 3.3.

Well, not quite. Longjump crashes and non-local goto crashes have been fixed, but trampoline crashes not. The gcc-3.2.x trampoline patch can be applied to gcc-3.3 and it fixes most trampoline crashes, but ..... ./test_run: line 193: 766 Segmentation fault "$DIFF" testmake.tmp "$xo" TEST fproc.pas: failed ... running the testuite for fproc.pas takes a long time and fails. After a while the hardddisk starts to spin continuously, which might indicate that the system is allocating lots virtual memory (on a 1.25 GB Mac). After this, gpc1 crashes when compiling ANY .pas file, until a reboot. The typical backtrace looks like this: Date/Time: 2003-05-18 03:11:07 +0200 OS Version: 10.2.4 (Build 6I32) Host: G4.local.
