--- Comment #7 from Lauri Kasanen <cand at gmx dot com> ---
Latest trunk (214073) is still broken.
Using latest trunk, I tried all optimization sub-options in
O2 to find the smallest hammer that fixes it.
-O2 -fno-thread-jumps: crash
-O2 -fno-align-functions: crash
...
-O2 -fno-use-caller-save: crash
The only combos that worked:
-O2 -fno-inline-small-functions: works
-O2 -fno-strict-aliasing: works
Moving to -O1 with those:
-O1 -finline-small-functions: works
-O1 -fstrict-aliasing: works
-O1 -fstrict-aliasing -finline-small-functions: crash
This does point to the code being wrong somehow, but in that case,
-Wall -Wextra should say something, and this would be a missing warning
bug in gcc.
