[Bug c++/99737] [modules] malloc(): smallbin double linked list corrupted

[alexander.lelyakin at googlemail dot com]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99737

--- Comment #3 from Alexander Lelyakin <alexander.lelyakin at googlemail dot com> ---
And the sequence from comment 1 has changed its error message to:

corrupted double-linked list
corrupted double-linked list
g++: internal compiler error: Aborted signal terminated program cc1plus
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://gcc.gnu.org/bugs/> for instructions.

Today's sequence is:

Repeatedly running this sequence i have found that it produces little different
error messages every time.
