raised STORAGE_ERROR : stack overflow or erroneous memory access
make[3]: *** [make.o] Error 1

I've seen this both on hppa2.0w-hpux11.11 and hppa1.1-hp-hpux10.20.

It appears to be a garbage collection problem.

[Bug ada/24994] raised STORAGE_ERROR : stack overflow or erroneous memory access

[ebotcazou at gcc dot gnu dot org]

------- Comment #15 from ebotcazou at gcc dot gnu dot org  2007-03-27 22:37 -------
Dave, does the problem still exist on the 4.2 branch for the PA?  I'm
now seeing it (same backtrace) on a patched 4.1 branch for x86-64.

No.  Ada builds successfully on all PA targets that support it
on both 4.1 and 4.2.  However, my 4.1 builds aren't very recent.
All results are posted.

Don't remember what fixed comment #13.  Possibly, a change just
made the issue latent.

Dave

OK, thanks.  Here is what I needed on my 4.1 branch:
