Bug report for Octave 3.2.0 configured for x86_64-pc-linux-gnu
Description:
-----------
* I meant to write
n=200; e=ones(n,1); A=spdiags([e 4*e e], -1:1, n, n);
but instead wrote
n=200; e=ones(n,1); A=spdiags([e 4*e e], -1:1, n);
which led to the error
error: A(I,J,...) = X: dimensions mismatch
error: called from:
error: /usr/share/octave/3.2.0/m/sparse/spdiags.m at line 71, column 29
error: /usr/share/octave/3.2.0/m/sparse/spdiags.m at line 76, column 7
however, when running the same erroneous command again, I got
octave: symtab.h:1065: static void symbol_table::force_variable(const std::string&, int, size_t): Assertion `xcurrent_context == 0' failed.
panic: Aborted -- stopping myself...
attempting to save variables to `octave-core'...
save to `octave-core' complete
Aborted
