if you want something fun to happen, run `c++filt _ZN8iloveyouIS_S_S_S_S_EIS0_S0_S0_S0_S0_EIS1_S1_S1_S1_S1_EIS2_S2_S2_S2_S2_EIS3_S3_S3_S3_S3_EIS4_S4_S4_S4_S4_EIS5_S5_S5_S5_S5_EIS6_S6_S6_S6_S6_EIS7_S7_S7_S7_S7_EIS8_S8_S8_S8_S8_EIS9_S9_S9_S9_S9_EE`

in case you're wondering, that's a DoS against demanglers, a symbol that expands to a signature that's at least 4GB long

I put `void [see above]() {}` in a file, compiled it, opened the object with Binary Ninja and it allocated so much the entire system instantly ground to a halt, nice people with IDA: does this also work against IDA, I wonder?

Doesn't seem to do anything to IDA 6.95 (don't have 7.x on this machine). It just doesn't demangle it. No evidence of slowdown or anything interesting. Maybe their demangler is more restrictive though?

Honestly I wouldn't be surprised if it just doesn't support some feature you're using. Do you have a non-DoS minimal example using the same features/constructs?

_ZN3fooIS_EE also try _ZN3fooIS_EEvv
