std::bad_alloc at read_vtu

[LY XXXiao]

Dear Dealii_group,

I encounter a memory problem at reading vtu file when I compile with dealii.9.50 but not with 9.40. 
When I compile with 9.40 (cmake -DDEAL_II_DIR=/data/libs/dealii-9.4.1 .) and 'make run', it will output: " Reading vtu file with cells:260 " (which is the correct output);
When I compile with 9.50 (cmake .)  and 'make run', it will output: "terminate called after throwing an instance of 'std::bad_alloc; what():  std::bad_alloc'"

I am wondering, if it is my mesh file is incorrect or there is some bug hidden in th enew version dealii ? (Attached please find the test script)

Thank you in advance for whoever gives some comments on this :)

Have a brilliant holiday season,

Longying

Hi all,

I think I found the reason. It's because I was using older version of dealii generating the vtu file and therefore can only read through older version.

Happy new year,

Longying

Yes, that sounds plausible.
