/* The msys2 seems to make a buffer overflow of EnvOfStackmachine[]. |
|
The code |
|
[(x) ring_of_differential_operators 11] define_ring |
|
( Dx*(x+Dx) ) /ff set |
|
causes the segfault because Mp_zero is borken. Is it a bug of msys2? |
|
Anyway, the following definition seems to be a workaround. 2015.09 |
|
Singnals do not work properly on msys2. (gcc -dM -E ... to see macros defs) |
|
See stackm.h |
