[Bug libmudflap/26446] New: Running large program compiled with mudflap aborts even before reaching main()

["walter dot zimmer at dlr dot de" <gcc-bugzilla at gcc dot gnu dot org>]

We're currently trying to get our binary mudflapped with gcc 4.1-20060217.
Compiling with -fmudflap works (for the C code; FFLAGS omits -fmudflap),
linking with -lmudflap is also no problem.

When calling the binary, we get:
bash> ./testbin
Operating system error: Success
Memory allocation failed

Gdb tells me that it doesn't even reach main(), and the mudflap environment
variables have no effect. I guess mudflap just gives up when beeing used on
such a large binary, but I don't find anything on this error messages on google
and I wonder if it's documented somewhere.

In any case, if the cause is a memory allocation problem of mudflap, perhaps
the error message should be more specific about what one can do or it should be
documented somewhere, so perhaps this is only a documentation enhancement
request.

If on the other hand debugging of a 4 mb executable should be supported, I
wonder what I can do to trace this error down.
