The crash tool failed to initialize on LoongArch64 when using GDB 16.2 (and likely other recent GDB versions that have enhanced LoongArch support) due to the error: "fatal error: buffer size is not enough to fit register value". This occurs in supply_registers() because GDB now correctly reports the size of LoongArch LASX (256-bit) vector registers (xr0-xr31) as 32 bytes. The `regval` buffer in `crash_target.c` was previously fixed at 16 bytes. This patch increases the `regval` buffer size to 32 bytes to accommodate the largest LoongArch registers reported by GDB. This allows crash to initialize successfully.
