[Tinycc-devel] bug report (cannot cast 'const struct foo' to 'struct foo')

[Brian Gough]

Hi,
I encountered a problem compiling some code with tcc-0.9.19.
Below is a test case which reproduces it.

I've checked that the previous version of tcc-0.9.18 compiled the same
code without errors.

I hope this is useful info.

best regards

p.s. Thanks for making tcc free software -- it's great!
