5 years ago I've tracked down this one to a buggy behavior arising from patterns with exception-handling code that only seem to appear with -O0 compilation. Running regressions now.

5 years ago The latest version of the WIP-taskinfo branch seems to fix this issue.
The code can be found in https://github.com/wheatman/extended-csr/tree/old_stuff/extended-csr2
With the following code cilk_for (uint32_t i = 0; i < n; i++) { cilk_for (uint32_t j = 0; j < n; j++) { // find_value returns 0 if not found. uint32_t value = g->find_value(i, j); if (value != 0) { add_edge(i, j, value); } } }
The compiler crashes with the error at the bottom
If I change either of the cilk_for loops to normal for loops the error goes away
Note this is not an issue on master, but rather with WIP-taskinfo
