The recursive call chain dsl_scan_visitbp() -> dsl_scan_recurse() -> dsl_scan_visitdnode() -> dsl_scan_visitbp has been observed to consume considerable stack resulting in a stack overflow (>8k). The cleanest way I see to fix this with minimal impact to the existing flow of code, and with the fewest performance concerns, is to always inline dsl_scan_recurse() and dsl_scan_visitdnode(). While this will increase the function size of dsl_scan_visitbp(), by 4660 bytes, it also reduces the stack requirements by removing the function call overhead. Issue #174 |
