Bug 29103
| Summary: | make (1) dump core while processing ^C from console with malloc's "recursive call." diagnostic. | ||
|---|---|---|---|
| Product: | Base System | Reporter: | andrew <andrew> |
| Component: | bin | Assignee: | Hartmut Brandt <harti> |
| Status: | Closed FIXED | ||
| Severity: | Affects Only Me | ||
| Priority: | Normal | ||
| Version: | 5.0-CURRENT | ||
| Hardware: | Any | ||
| OS: | Any | ||
Responsible Changed From-To: freebsd-bugs->harti I take this. The reason for the core is quite obvious from the backtrace: the interrupt handler CompatInterrupt call free() which it shouldn't do. In general interrupt handlers are allowed to call only a small number of functions. This will require some work, though. State Changed From-To: open->closed Fixed in RELENG_6 by not doing the interrupt processing from the signal handler. |
