Problems with Symbols, Medium Severity (1)

	Change	Effect
1	The pointer level of return value has been decreased from 1 to 0.	Applications may try to access unallocated memory by the dereferencing of new return value and therefore cause a crash.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Base type has been changed from fftw_plan_struct* to fftw_plan_s*.	Possible incorrect initialization of parameters by applications.

Problems with Symbols, Low Severity (13)

	Change	Effect
1	1st parameter plan has been renamed to p.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter emitter has been renamed to write_char.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter f has been renamed to p.	Renaming of a parameter may indicate a change in its semantic meaning.
2	2nd parameter plan has been renamed to output_file.	Renaming of a parameter may indicate a change in its semantic meaning.
3	Base type of 2nd parameter plan has been changed from fftw_plan_struct (48 bytes) to _IO_FILE (148 bytes).	Memory stored by pointer may be incorrectly initialized by applications.
4	Base type of parameter f has been changed from _IO_FILE to fftw_plan_s of different format.	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	1st parameter g has been renamed to read_char.	Renaming of a parameter may indicate a change in its semantic meaning.
2	Type of return value has been changed from fftw_status to int.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from fftw_status to int.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	Type of return value has been changed from fftw_status to int.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter plan has been renamed to p.	Renaming of a parameter may indicate a change in its semantic meaning.
2	Base type of parameter plan has been changed from fftw_plan_struct to fftw_plan_s of different format.	This parameter may be incorrectly initialized by applications.

	Change	Effect
1	Type of this global data has been changed from char const* to char[] const.	Replacement of data type may indicate a change in semantic meaning.

Problems with Constants (2)

	Change	Effect
1	The value of constant FFTW_ESTIMATE has been changed from (0) to (1U << 6).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant FFTW_MEASURE has been changed from (1) to (0U).	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
