Zeniko, thank you for spotting and reporting the typos. They have now been
committed as 9cddb4c193c6123140c6f7b1960db34025f86e40

However, please note that the following changes have not been included :-

1) "check = ((int64_t)stride)*((int64_t)height) + 1;"
See the reasoning in comment #3 above relating to Bug690723.

2) "/* SumatraPDF: this looks more correct */ jbig2_free(ctx->allocator,
dicts);"
The original code is correct and frees the memory accordingly.

3) "/* SumatraPDF: fix memory leak */ jbig2_free(ctx->allocator, dicts);"
The dicts are freed during segment release, freeing them early here would cause
a crash later in the process. This is not visible with the attached example
file because it does not enter this code path.
