Bug ID: 125758
Summary: [17 regression] ICE in ranger (stack overflow) when
building qgis
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: compile-time-hog, ice-on-valid-code
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
Reported to me by Paul Zander (negril).
It doesn't crash for me without Valgrind but it does with. For him, it fails
always.
```
$ g++ foo.ii -c -march=znver3 -mshstk -wrapper valgrind,-q
==430399== Stack overflow in thread #1: can't grow stack to 0x1ffe001000
==430399== Can't extend stack to 0x1ffe000d98 during signal delivery for thread
1:
==430399== no stack segment
==430399==
==430399== Process terminating with default action of signal 11 (SIGSEGV):
dumping core
==430399== Access not within mapped region at address 0x1FFE000D98
==430399== Stack overflow in thread #1: can't grow stack to 0x1ffe001000
==430399== at 0x55C8C48: fold_using_range::range_of_range_op(vrange&,
gimple_range_op_handler&, fur_source&) (gimple-range-fold.cc:734)
==430399== If you believe this happened as a result of a stack
==430399== overflow in your program's main thread (unlikely but
==430399== possible), you can try to increase the size of the
==430399== main thread stack using the --main-stacksize= flag.
==430399== The main thread stack size used in this run was 16777216.
